Naomi has earned $78 mowing lawns the past two days. She worked 4 1/2 hours yesterday and 5 1/4 hours today. If Naomi is paid the same amount for every hour she works, how much does she earn per hour to mow lawns? How much does Naomi earn per hour?

Answer 1

Answer:

Hourly rate= $8/hr

Amount she made in the two days- 1st day: $36 2nd day: $42

Step-by-step explanation:

Make the fractions the same denominator: 1/2 = 2/4

So 4 1/2 becomes 4 2/4

4 2/4x + 5 1/4x = 78

9 3/4x = 78

9 3/4x ÷9 3/4 =78 ÷ 9 3/4

X= 8

Amount per day (Times the hours worked converted to decimals 4 1/2 = 4.5 , 5 1/4= 5.25  by the hourly rate: 8)

4 1/2 * 8 = 36

5 1/4 * 8 = 42
