Find the pay for 35 hours of work.

Question

A person's salary (P) varies directly as a number of hours (h) of hours of work. For working 15 hours, the pay is $29.60. Find the pay for 35 hours of work.

Answer 1

pay varies directly to the number of hours worked

p = kh  where p is pay, h is number of hours worked, k is constant of variation

 

29.60 $ = 15 hours k

Solve for k to find constant of variation

k = 29.60 $/15 hours

k = 1.97  (approx)  

 

p(35) = 8.25h

p= 8.25(35) =$69.07
