Given:
Given the word problem, we can deduce the following information.
1. Amanda has $616.78 in her checking account.
2. She deposited 42.66 and $83.44.
3. She writes checks for $33.69, $54.57, and $9.35.
To find the new balance in her checking account, we use the formula:
New balance= Previous Balance+ Deposits-Withdrawals
Based on the given information, we let:
Previous Balance = $616.78
Deposits = $42.66 + $83.44 = $126.1
Withdrawals = $33.69 + $54.57 + $9.35 =$97.61
We plug in what we know in the formula:
New balance= Previous Balance+ Deposits-Withdrawals
= $616.78 +$126.1-$97.61
Calculate
New balance= $645.27
Therefore, the answer is $645.27.
