The amount of money you earn varies directly with the number of hours you work. You work 8 h and earns $98. How many hours do you need to work to earn $441?

Question

Has to be in the form of y = mx +b

Answer 1

The amount of money you earn varies directly with

the number of hours worked....  y = kx    where

y is money earned, k is $/hr pay rate, x = hours worked

 

98 = k(8)    You earn $98 for 8 hours of work

k = 98/8

k = 12.25

 

Your hourly pay rate is $12.25

y = 12.25x

 

441 = 12.25x

x = 441/12.25

x = 36 hours

 

It takes 36 hours of work to earn $441
