Question

QUICK ANSWER PLEASE. 

 

Thank you very much.

Answer 1

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.

Answer 2

27 = 3k

9 = k

y = 9x
