1. Benjamin earned 9 1/4 per hour for 8 hours of work on Saturday. His manager asked him to stay an additional 2 hours, for which he was paid 1 1/2 times the regular rate. How much did Benjamin earn on Saturday?

2. A ship is running at 7 1/8 knots (neautical miles per hour) for 8 1/2 hours. How far does the ship travel?

3. Mika earns $900 per week. She has 1/5 of her income taxes, 1/15 of her income withheld for state taxes, and 1/20 of her income withheld for medical coverage. How much per week is left for Mika after these three deductions?

-
1) $ = 9 1/4 * 8 + 9 1/4 * 1 1/2 *2 = 101 3/4 (or 101.75)
2) 7 1/8 * 8 1/2 = 60 9/16 ( or 60.5625)
3) 900 - (900*1/5 + 900*1/15 + 900*1/20) = 615

-
1.
9.25 x 8 = 74
13.875 x 2 = 27.75
total = 101.75

2.
7.125 x 8.5 = 60.5625

3.
900 x .2 = 180
900 x .0666667 = 60
900 x .05 = 45
900 - 285 = 615 left

-
1 - 9.25*8 +1.5*9.25*2 = 101.75

2 - 7.125*8.5 = 60.5625

3 - 900-(900/5)-(900/15)-(900/20) = 615
