Suppose you earn $15 for each car you wash. which function describes the relationship between your total earnings e and the number of cars you wash c?

E(c) = 15c

Step-by-step explanation:

If I earn $15 for each car i wash and my total earnings are E then we have to form a function which describes this relationship.

My earning for one car wash = $15

Similarly my earnings for c car washes = $15×c

This total earning is equal to E so function representing the equation will be E(c) = 15c

Answer is E(c) = 15c which describes the relashionship of my earnings to the number of cars i wash.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
