What is his hourly wage

Question

Suppose that bob is paid two times his normal hourly rate for each hour he works over 40 hours in a week. Last week he earned $504 for 48 hours of work. What is his hourly wage?

Answer 1

let w = Bob's wage

 

(Normal hours * w) + (overtime * double w) = salary

40w + 8(2w) = 504

40w + 16w = 504

56w = 504

w = 9
