Question

Tommy's weekly pay is directly proportional to the number of hours he works at the movie theater. His pay is $189 for 21 hours. Find the amount of pay for 40 hours of work.

Answer 1

Explanation:

r = 189/21

r = 9

Now, to find the amount he is paid, the equation is as follows:

y = rx

For 40 hours, the equation is:

y = 9(40)

y = 360

Answer 2

We need to find the amount Tommy is paid per hour. This is simple:

r = 189/21
r = 9

Now, to find the amount he is paid, the equation is as follows:

y = rx

For 40 hours, the equation is:

y = 9(40)
y = 360
