Sue has a balance of $35in her checking account. She writes one of the check for$10, and three checks for $9 each what is her balance now

We have to subtract the total of the written checks from the total money in her balance; so first lets add the total of the checks:

$10 + $9 + $9 + $9 = $37.00

Now that we found the total money of checks we must now subtract it from the balance:

$35 - $37 = - $2.00

So her ending balance is - $2.00
