Calculate the paychecks of the following people. They make time and a half for any hours beyond 40. Round all values to two decimal places.

Answer:
Sue Black: 40 hours, $270
Jerry Atrix: 30 hours, $154.50
Sam Ting: 38.75 hours, $339.06
Step-by-step explanation:
Firstly, 40 hours is a workweek of 8-hour shifts. It's good to remember. Otherwise, we can multiply 8 by 5 and get 40 anyway. That's the hours of Sue Black, and she earns:
40*$6.75 = $270
Jerry worked for (note you can easily add in memory if you do the fractions first):
7.25+3+6.75+8+5 = 7.25+6.75 + 3+8+5 = 14 + 16 = 30
Earnings:
30*$5.15 = $154.50
Sam worked a quarter of an hour less than Sue each day. That means that his total time was:
40 - 5 * 0.25 = 40 - 1.25 = 38.75
Earnings:
38.75*$8.75 = $339.0625 ≈$339.06
