Question

Ms. Donaldson earns $18.80 per hour for the first 40 hours she works in a week. She earns 1 ½ times that amount per hour for each hour beyond 40 hours in a week. Last week Ms. Donaldson worked 45.5 hours. How much money did she earn?

Answer 1

You take $18.80 divide by 2 =$9.40 then $18.80+$9.40=$28.20
$28.20 x's 5.5=$155.10
$18.80 x's 40=$752.00
then add 752.00+155.10=$907.10

Answer 2

First, you would multiply 18.80 times 40 and get 752. 
Then you would multiply 18.80 times 1.5 and get 28.2 and multiply that times 5.5 and get the answer 1,062.2
