Isaac started the week with $78 in his bank account. After depositing a paycheck, the balance was $298. What was the amount of Isaac's paycheck?

$220

Step-by-step explanation:

Knowing that he started with $78 we can take the end amount ($298) and subtract it by the amount he started with ($78).

$298 - $78 = 220

We know that his last paycheck was $220

First Divide: 21.75/ 30

You will get 0.725

Then, multiply 0.725 by 100%

Then your answer should be: 72.5%
