Mary earns $12 per hour, plus 10% commission on all her sales. Mary worked 10 hours and her sales were $1,500. How much money
did Mary earn?

Answer 1

First, you multiply 12 and 10 to get how much money she earned in 10 hours.  She earned 120 dollars in 10 hours.  Next, you multiply 10% and 1500.  You turn 10% into 0.10, and multiply by 1500 to get 150.  Finally you would add 150 and 120 to get $270.  Mary earned $270.
