Eric wants to sell his car that he paid $7,000 for three years ago. The car depreciated, or decreased in value, at a constant rate each month over a 3-year period. if he x represents the monthly depreciation amount, which expression shows how much Eric can sell his car for today?

c

Step-by-step explanation:

C  7.000 - 36x

Step-by-step explanation:

x = depreciated each month

3 years = 36 months (12 x 3 =36)

7000 (car) -36x  (depreciated )

= 7.000 - 36x

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!
