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
