Bruce earns 1.5 times his normal hourly rate for each hour he works after 40 hours in a week. He worked 53 hours this week and earned $833. What is his normal hourly rate?

Let x = hourly rate and
1.5x = overtime rate.

40*x + 13*1.5x = 833
Solve for x. 
40(x)+13(1.5x)=833
=40x+20x=833
=60x=833
x needs to be isolated, so divide 60 from 833
x=833/60
x=14
hourly rate =$14.00
overtime rate=1.5(14)=$21.00 
Where did you guys get the 13 from?

5340 = 13
