Question

Calebs weekly pay is directly proportional to the number of hours he works at a grocery store. his pay is $169 for 22 hours of work. write an equation in the form of y=ax then find the amount of pay for 40 hours of work.

what is the y?
what is the x?
what is the a?

Answer 1

y is the total pay

x is the hours worked

a is the rate per hour

y = ax

Let's find "a", the rate per hour

He worked 22 hours and made $169. Substitute those numbers in our equation y=ax.

169 = a*22

169/22 = a

7.68181818182 which is approx $7.68

so our equation is y=7.68x

If he works 40 hours:

y=7.68x

y = 7.68 *40

y = 307.20

So 40 hours of work = $307.20
