Question

One Saturday, Sam and Joe worked together to mow lawns. Sam started at 8:00 AM and Joe started at 11:00 AM. When they finished at 4:00 PM, they had earned a total of $156. They want to share the money they earned fairly based on the number of hours worked. How much should Joe receive?

Answer 1

Joe worked 5hrs
Sam worked 8hrs
In total they worked 13hrs
Divide 156 by 13
They earned $12 an hour
12 times 8 = $96
5 times 12 = $60
Joe should recieve $60
Sam should recieve $96

Answer 2

Sam worked from 8am to 4pm, for a total 8 hours. 
Joe worked from 11 am to 4 pm, for a total of 5 hours. 

Combined, they worked 8 +  5 = 13 hours, and earned $156. 
That means they earned 156 ÷ 13 = $12 per hour

Sam worked 8 hours, so he should receive 8 * 12 = $96

Joe worked 5 hours, so he should receive 5 * 12 = $60

Answer is $60
