Mr. Evans is paid $9.20 per hour for the first 40 hours he works in a week. He is paid 1.5 times that rate for each hour after that.
Last week, Mr. Evans worked 42.25 hours. He says he earned $388.70 last week. Do you agree? Support your answer.
Disagree. The learnings for 40 hours are $9.20 x 40 = $368. $9.20 x 1.5 = $13.80, which is the rate for each hour over 40. $13.80 x 2.25 =$31.05. I added $31.05 + $368 = $399.05
