Sandy works at a clothing store. She makes $7 per hour plus earns 10% commission on her sales. She worked 70 hours over the last two weeks and had a total of $2,980 in sales before taxes.

Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

interest rate - 12.000%  

final payment - $355.40

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
