Question

Joann works in a publicity office at the state university. she is paid $ 12.00 $12.00 an hour for the first 35 35 hours she works each week and $ 18.00 $18.00 an hour for every hour after that. if she makes $ 636.00 $636.00 one week, how many hours did she work?

Answer 1

$ 12 per hr for the first 35 hrs.....12 * 35 = 420

420 + 18x = 636
18x = 636 - 420
18x = 216
x = 216/18
x = 12

so she worked 35 hrs regular pay and 12 hrs overtime for a total of 47 hrs
