Math of Finance: Chapter 2 Test
When we left James, he had decided to take a job at Jimmy John's as a sandwich artist with an expected salary of
$31,200 per year. James is really looking forward to the pay increase to help take care of his wife and two kids
After working four weeks, he gets his first check. It is much less than he expected. It turns out he will only get paid
for two weeks because Jimmy John's has a delayed paying process. Everyone gets paid two weeks after they work to
give Human Resources time to prepare the tax information. Since James gets paid every two weeks, a)what is his
gross income for his checks? His pay was much less. It tums out, other people get his money first. He had to pay
Federal Income Tax. b)Use the chart on the back of the test to determine his FIT. He also has to pay State
Income Tax. Oklahoma has a flat 5% tax. c)What is his SIT at 5% of his paycheck? Also, something called FICA
was on his paystub. His employer told him it was a required 6.2% tax for Social Security Retirement and a 1.45%
tax for Medicare when he gets older. d)Find James' Social Security Tax. e)Find his Medicare Tax. What is the
amount of FICA Tax listed as being withheld(add together)? Next came the big schock. Apparently, the
Republican Party still hasn't ended required healthcare. Because of this, James has to pay for group insurance with
Jimmy John's. It is $100 every paycheck, g)what percent of James' gross income is this each month? Finally,
James looks at the other category. It has two deductions listed. First, it has Sandwich Union Body Dues. Annual
dues are $130. h)How much was taken out for SUB dues just this paycheck? The second charged deduction for
other was IRA Retirement. He remembers signing up because Jimmy Johns' offers a matching 5%. If James' is
maximizing the match, i)how much is being taken out for retirement from his paycheck? After going over all the
numbers with his boss, it looks like James' check is correct. j)How much was his net income? If these numbers
remain consistent through the year, k)how much will James bring home for the year? DWhat percent of his
expected salary is this? James was really looking forward to his big paycheck. He thought he would have enough
money to get a loan on a new car. m)Do you think he should try to get the loan or not? n>Explain your opinion.

Answers
Step-by-step explanation:
multiplying expressions.
remember every term of one expression has to be multiplied with every term of the other expression, and the results are added up (while considering their individual signs, of course).
1.
(-3×3 + 2x - 4)(3x - 2)
(-9 + 2x - 4)(3x - 2)
(-13 + 2x)(3x - 2) = -13×3x + -13×-2 + 2x×3x + 2x×-2 =
= -39x + 26 + 6x² - 4x = 6x² - 43x + 26
2.
let's do the other multiplication and compare the result with the result of 1 :
(-13 + 2x)(2x - 3) = -13×2x + -13×-3 + 2x×2x + 2x×-3 =
= -26x + 39 + 4x² - 6x = 4x² - 32x + 39

Lexi is at the top of the Sunshine Skyway Bridge, traveling on I-275 from Bradenton, FL, and heading into St. Petersburg to see her favorite band play a concert. If the top of the Sunshine Skyway Bridge is 175 feet tall and she sees a boat that appears to be at an angle of depression of 35°, what is the distance from the top of the Sunshine Skyway Bridge to the boat? (That means you are measuring from the top of the bridge and you are not including the height of the boat.)
Answers
The distance from the top of the Sunshine Skyway Bridge to the boat is 305.1 feet.
What do we mean by trigonometric ratios?The values of all trigonometric functions dependent on the value of the ratio of sides of a right-angled triangle are known as trigonometric ratios. The trigonometric ratios of a right-angled triangle's sides with regard to any of its acute angles are known as that angle's trigonometric ratios.
The three sides of the right-angled triangle are:
Hypotenuse (the longest side)
Perpendicular (opposite side to the angle)
Base (Adjacent side to the angle)
The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
The trigonometry ratios for a specific angle ‘θ’ is given below:
Trigonometric Ratios:
Sin θ = Perpendicular/Hypotenuse
Cos θ = Base/Hypotenuse
Tan θ = Perpendicular/Base or Sin θ/Cos θ
Cot θ = Base/Perpendicular or 1/tan θ
Sec θ = Hypotenuse/Base or 1/cos θ
Cosec θ = Hypotenuse/Perpendicular or 1/sin θ
How do we solve the given question?Let the tower be AB = 175 feet, with the top of the tower as A.
Let the top of the boat be C. We join BC to get a right-angled triangle ABC with ∠B = 90°.
We are told that from the top of the tower, Lexi sees a boat at an angle of depression of 35°, represented as ∠CAD. ∠ACB will be equal to this angle as they are alternate angles.
∴ ∠ACB = 35°.
Let the distance from the top of the boat to the top of the tower be feet, the distance CA, the hypotenuse of the triangle ABC.
∴ By trigonometry, we can say that:
sin 35° = AB/BC
or, 0.5736 = 175/x
or, x = 175/0.5736
or, x = 305.1
∴ The distance from the top of the Sunshine Skyway Bridge to the boat is 305.1 feet.

2) Lucas has saved $50. He earns
$18.00 per hour at his job. He plans to
buy ticket to go on a cruise for $2300.
Write the minimum number of hours
Lucas must work to buy the ticket.
Answers
Answer:
125 hours
Step-by-step explanation:
Lucas already has $50. Since he get $18 per hour, you should use that to get the answer. After a little while, I got 125×18 and got 2250. If you add up the $50 he already has, the minimum hours he has to work is 125 hours which is about 5 days.
Answer:
I think the answer is 125 hours
Step-by-step explanation:
To find the unit rate we divide $2300 divided by $18.00
$2300 ÷ 18 = 127.777778
We round that up to 128
We also need to find the unit rate of his saved money
$50 ÷ $18.00 = 2.77777777778
We round that up to 3
128 hours - 3 hours = 125 hours

Answers
Answer:

Step-by-step explanation:
KJ = LM
⇒ x + 31 = 5x - 9
⇒ 40 = 4x
⇒ x = 10
From inspection of the diagram, m∠K = 90° (right angle)
KL = JM
⇒ 4y + 5 = 2y + 35
⇒ 2y = 30
⇒ y = 15
JM = 2y + 35
⇒ JM = 2(15) + 35
⇒ JM = 30 + 35

Fiona is x years old thomas is 3 years older than fiona cara is twice as old as fiona the sum of their ages is 51
Answers
Thomas= x+3
Cara= 2x
Therefore x+2x+x+3=51
4x=48
x=12
The ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Fiona who is [x] years old. Thomas is 3 years older than Fiona. Cara is twice as old as Fiona the sum of their ages is 51.
We can write -
Age of Thomas = [y] = x + 3
Age of Cara = [z] = 2x
and
2x + x = 51
3x = 51
x = 17
Age of Thomas = [y] = x + 3 = 20
Age of Cara = [z] = 2x = 34
Therefore, the ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.
