Answer:
$42.00
Explanation:
So, something hasn't been subtracted from your bottom line. The bank is saying you only have $26.33. You think you have $68.33.
Let's look for the difference. This is one of those great times when the word in english and the word in math have the same meaning. Difference is telling us to subtract.
68.33 - 26.33
= 42.00
Check:
If you subtract the missing entry, $42.00 from your total,
68.33 - 42.00
you get $26.33, exactly the balance the bank says you have. Now your account is balanced!
