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
