A customer will borrow $12,000 to buy a car. Which loan option would allow
the customer to pay the least amount of interest?
A 4-year loan with a 5.2% annual simple interest rate
A 5-year loan with a 4.2% annual simple interest rate
A 6-year loan with a 4.7% annual simple interest rate
O
A 3-year loan with an 8.4% annual simple interest rate
Answers
Answer:
number one is the best one
The loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.
Calculation of loan with least simple interest rateFormula for simple interest = P ×T × R/100
P = Principal amount borrowed ($12,000)
T = Time in various years given
R = Rate of simple interest generated
To determine which loan option that would allow the customer to pay the least amount of interest, the simple interest of each option is calculated below
Simple interest of a 4 years loan = 12000×4×5.2/100
= $2,496
Simple interest of a 5 years loan= 12000×5×4.2/100
= $2,520
Simple interest of a 6 years loan= 12000×6×4.7/100
= $3,384
Simple interest of a 5 years loan= 12000×3×8.4/100
= $ 18,144
Therefore, the loan option that will allow the customer to pay the least amount of interest is 4-year loan with a 5.2% annual simple interest rate.

A school held a special math event for parents. On the first night, 150 parents attended, which was 40% below the expected attendance. On the second night, 210 parents attended, exceeding the expected attendance by 40% . By what percent did the actual attendance at the special math event exceed or fall below the expected attendance for both nights?
Answers
Answer:
10.429% exceed
Step-by-step explanation:
expected:
150x [100+40]/100=210 parents were expected on first night
210x60/100=126 parents expected on the second night
210+126=326 expected
percentage difference=
210+150=360
360/326 x 100=110,429%
110,429%-100%=10,429% exceed

Answers
Answer:
She'll need 3 more hours to complete the project
Step-by-step explanation:
Because (3/4) × (4/3) = 1, you can multiply 9 by 4/3 to find the total amount of time needed for the project. You'll get a total time of 12 hours. To find how many more hours needed you would do 12 - 9 = 3 hours

What is the rate of decay, r (expressed as a decimal), for data best modeled by the exponential function y equals 3.31 left parenthesis 0.87 right parenthesis superscript x baseline?
r = 0.13
r = 0.87
r = 2.88
r = 3.31
Answers
The rate of decay r is -0.139.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The exponential function [tex]y = 3.31(0.87)^x[/tex] can be written in the form
[tex]y = ab^x,[/tex]
where a = 3.31 and b = 0.87.
The formula for the rate of decay for an exponential function in the form
[tex]y = ab^x[/tex]is r = ln(b)
where ln is the natural logarithm.
In this case,
r = ln(0.87) ≈ - 0.139.
Since r represents the rate of decay as a decimal, the answer is r = - 0.139.
Thus,
The rate of decay r is - 0.139.

64 + 3x = 70 subtract 64 from both sides
