Mr. evan 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. evan worked 42.25 hours he says he earned $3888.70 last week do you agree support your answer

That is incorrect. The correct answer should be $398.38
First you take 9.2 times 40 and you get $368 which is how much he got paid for the first 40 hours. now he worked 2.25 hours extra so you take 9.2 * 1.5 because he gets 1.5 times more for extra hours. Then you add that to the $368 and you get $398.38
