Answer:
$89.25
Step-by-step explanation:
This would be a fairly simple addition and subtraction problem. The initial balance of the register is $845.50, the owner then added a deposit of $152.73 which is added to the initial balance.
$845.50 + $152.73 = $998.23
Next, he wrote three checks which means those values are subtracted from the current balance like so...
$998.23 - $682.67 - $146.05 - $99.33 = $70.18
This leaves the balance at $70.18, the owner wants to add an additional two checks which would leave the balance at...
$70.18 - $75.81 - $83.62 = -$89.25
Meaning he would have to deposit $89.25 before writing the two checks or he would not have enough in the register to support those checks.
