Answer:
E(c) = 15c
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.
