D. Worker B earns more per day than worker A and more per hour than worker A.

Answer 1

Worker A:
Total earning per day = $8.10 x 10 = $81

He works 9 hours a day.  Find the rate for 1 hour.
81 ÷ 9 = 9
He earns $9 an hour

Worker B:
Total earning per day = $8.40 x 8 = $67.20

He worked 7 hours a day. Find the rate for 1 hour.
67.20 ÷ 7 = $9.60
He earns $9.60 per hour

Worker A earns more per day than worker B but less per hour than worker B. (Answer B)
