Dominic earns $18 an hour plus $25 an hour for every hour of overtime. overtime hours are any hours more than 35 hours for the week. dominic earned $730 in 1 week. how many hours (regular plus overtime) did he work? show work.

He worked 39 hours in 1 week. Dividing $730 by $18 gives a decimal value therefore you have to start by multiplying $18 by 35 hours.

1. $18/hour  x   35 hours   = $630

2. $730 - $630 = $100.

3. There are no combinations of $18 and $25 that can come together to form $100 therefore there must have been 4 hours of overtime worked ($100 /$25  = 4)

4. 35 hours + 4 hours = 39 hours

Hope this helped
