7. Suppose you earn $15 for each car you wash. Which function describes the relationship
between your total earnings Eand 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.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
