Question

Prior to making deposits of $75 and $50 Marian had a balance of $102in her checking account. How much must she deposit so that her balance winbe at least $300 and she can avoid a service fee

Answer 1

Marian had a balance of $102

Then she made two deposits, one of $75 and the other for $50

We can calculate the balance of her checking account after the deposits were done

New balance = $102 + $75 + $50 = $227

The account needs to have at least $300 to avoid a service fee, so we calculate how much is needed to complete that amount

New deposit = $300 - $227 = $73

So, if Marian deposits at least $73, the account balance will be $300 or more

Answer: She must deposit at least $73
