Question

Naomi has earned $54 mowing lawns the past two days. she worked 2 1/2 hours yesterday and 4 1/4 hours today. if Naomi is paid the same amount for every hour she works, how much does she earn per hour the mow lawns?

Answer 1

2 1/2 + 4 1/4 = 6 3/4

6 3/4 = 27/4


`54/ (27)/(4) = 54* (4)/(27) = 2 * 4 = 8`

So Naomi earned $8 per hour that she mows the lawn.
