a. Write an equation that represents the situation.

Answer 1

Answer:
`(27)/(3)`

Explanation:

Answer 2

If the cost y is proportional to the number of hours x:

y = kx where k is the constant of proportion.

Given $27 for 3 hours, find k

27 = 3k

k = 9

Your equation is: y = 9x

From this, given a value for y or x you can plug it in to find the other.
