Answer:
$40.95
Step-by-step explanation:
First we need to find out how much he makes per hour. Take the total amount he makes and divide by the number of hours
Amount per hours = 18.20 ÷ 2 1/3
Change the mixed number to a improper fraction
2 1/3 = (3*2+1)/3 = 7/3
Amount per hours = 18.20 ÷ 7/3
Copy dot flip
Amount per hours = 18.20 * 3/7
$7.80 per hour
Now we want to find out how much he makes for 5 1/4 hours. Take the amount per hour times the number of hours
Total amount = 7.8 * 5 1/4
Change the mixed number to an improper fraction
5 1/4 = (4*5+1)/4 = 21/4
Total amount = 7.8 * 21/4
Total amount = 40.95
