Question

Naomi has earned $54 mowing lawns the past 2 days. She worded 21/2 hours yesterday and 41/4 hourse today. If Naomi is paid the same amount for every hour she works, how much does she earn per hour to mow lawns?

Answer 1

First day: 2 1/2= 2.5 hours
Second day: 4 1/4= 4.25 hours
When h is hours:
2.5h + 4.25h = 54
6.75h = 54
/6.75    /6.75
h= 8
Naomi charges $8 an hour to mow lawns. Hope this helps.
