Question

Harold earns $10.50 per hour working at a doctor’s office. On Monday he spent 1 5/12 hours filing paper work, 1 3/4 sending emails and 2 1/3 hour’s making appointments. What were Harold’s earnings?

Answer 1

Answer:$57.75

Explanation:

Find the total amount of hours he worked

`1(5)/(12) +1(3)/(4) +2(1)/(3)\\\\(17)/(12)+ (7)/(4) +(7)/(3) \\\\(17+21+28)/(12) \\\\(66)/(12)=(66/2)/(12/2)=(33/3)/(6/3)= (11)/(2) or 5(1)/(2) or 5.5h`

So, he worked 5.5h and he earns $10.50 an hour.

($10.50)(5.5h)=$57.75
