Question

Suppose you earn $15 for each car you wash witch function describes the relationship between your total earning E and the number of cars you wash

Answer 1

E= £15 times x because is the earnings and he gets £15 per car. We don't know him many cars he washes,so it would be x.

Answer 2

`E=15n`

Let n be the number of cars you washed

Cost of washing each car = $15

So, Cost of washing n cars = 15 n

Let the total earnings be E

So, the expression becomes :

`E=15n`

Hence function describes the relationship between your total earning E and the number of cars you wash is :

`E=15n`
