Answers
As per the given percentage,
a) Commission base in the sales base is $1400
b) Commission on additional sales is $2695
c) Gross pay is $4095.
Percentage:
Percentage is a number or ratio that can be expressed as a fraction of 100.
If we want to calculate percent of a number, divide the number by the whole and multiply by 100.
It can be represented using the symbol (%).
Given,
Bartlett Electronics pays all sales representatives 4% commission on the first $35,000 of their individual sales and 7% commission on their individual sales in excess of $35,000.
John Morgan sold merchandise valued at $73,500 during the month of November.
Here we need to find the following:
a) Commission on sales in the sales base
b) Commission on additional sales
c) Gross pay
a) Commission on sales in the sales base
So, based on the percentage the commission is,
=> 35,000 x 4/100
=> 35,000 x 0.04
=> 1400
b) Commission on additional sales
For this one, first we have to calculate the additional sales amount,
That can be calculated as,
=> 73,500 - 35,000
=> 38,500
Now, the commission is,
=> 38,500 x 7/100
=> 38,500 x 0.07
=> 2695.
c) Now the gross pay for John is,
=> 1400 + 2695
=> 4095
Therefore, the gross pay is $4095.

Find the probability that a randomly chosen point is the figure lies in the shaded region. Give all answers in fraction and percent forms.help with number 5 or all of them if u can pls
Answers
NUMBER 5:
INFORMATION:
We have a trapeze and, we need to find the probability that a randomly chosen point is the figure lies in the shaded region
STEP BY STEP EXPLANATION:
To find the probability, we must divide the area of the shaded region by the total area of the trapeze
[tex]\text{ Probability}=\frac{Shaded\text{ area}}{Total\text{ area}}[/tex]- Total area:
To calculate the total area, we must use the formula for the area of a trapeze
[tex]A_{trapeze}=\frac{(b_1+b_2)h}{2}[/tex]Where, b1 and b2 are the bases and h is the height
Then, analyzing the trapeze we can see that b1 = 20, b2 = 14 and h = 12
[tex]A_{total}=A_{trapeze}=\frac{(20+14)12}{2}=204[/tex]So, the total area is 204 square units
- Shaded area:
To find the shaded area, we must subtract the no shaded area from the total area.
We can see that the no shaded area is a rectangle with width = 14 and height = 12
Now, using the formula for the area of a rectangle
[tex]A_{rectangle}=\text{ width}\times\text{ height}=14\times12=168[/tex]Then, subtracting the area of the rectangle from the total area
[tex]A_{\text{ no shaded}}=204-168=36[/tex]So, the no shaded are is 36 square units.
Finally, the probability would be

A witch's brew calls for I 1/4 cups of

with 7 1/2 cups of water in it.
How many times can she

Answers
The witch can make her special brew 6 times with the amount of water present in the small frog pond.
Given that:-
Total amount of water present in the small frog pond = 7 and 1/2 cups = 15/2 cups
Amount of water the witch needs to make her special brew = 1 and 1/4 cups = 5/4 cups
We have to find the number of times Wendy the witch can make her special brew with the amount of water present in the small frog pond.
We know that,
Number of times the witch can make the brew = Total amount of water/Water needed for brew
Hence, by simple division, we can write,
Number of times the witch can make the brew = (15/2) ÷ (5/4) = (15/2)*(4/5) = 6 times.

You have $73.50. You earn additional money by mowing lawns. Then you purchase a new pair of shoes for $99.99 and have $23.51 leftmuch money do you earn mowing lawns?
Answers
The question provides the following information;
Money at hand = 73.50
Money earned = x
Purchases made = 99.99
Money left over = 23.51
These sets of numbers can be put into an equation as shown below;
(73.5 + x) - 99.99 = 23.51
This equation means what you had at the beginning plus what earned from mowing lawns is a total of 73.5 + x. Subtract the cost of shoes purchased from this total and you'll now have a balance of 23.51
We can now solve for the money earned from mowing lawns as follows;
(73.5 + x) - 99.99 = 23.51
Add 99.99 to both sides of the equation (in order to isolate the 73.5 + x on the left side of the equation). You now have;
73.5 + x = 123.5
Next you subtract 73.5 from both sides of the equation (in order to isolate the x on the left hand side)
x = 50
This means the money earned from mowing lawns is $50
