Frank wants to buy three items costing $111.32, $28.75, and $73.21. If he earns $8.75 an hour, how many hours must Frank work be

Sedaia [141]

The three items cost altogether is : 111.32 + 28.75 + 73.21 = 213.28

So, he must work 213.28 : 8.75 = 24.3748571429...

Since if he works 24 hours, he wouldn't have enough money to buy the 3 items, so he must work 24 + 1 = 25 hours.

Recheck : 25 x 8.75 = 218.75 ( > 213.28)
