Answer:
19 hours
Step-by-step explanation:
Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Step 1 find the number of driveways to shovel
25x = $831.25
x = $831.25/25
= 33.25 driveways
Step 2
He can shovel
14 driveways = 8 hours
33.25 driveways = x
Cross Multiply
14x = 8 × 33.25
x = 8 × 33.25/14
x = 19 hours
