Amy wrote a check for $32 to pay her monthly electricity bill, but when balancing her checkbook, she accidentally recorded it as a credit rather than as a debit . how will her check register compare to her monthly bank statement when she receives it ?

Her check register will have a surplus of 64 dollars compared to her actual balance. 
example
100 +32 = 132  (incorrect)
100 -32 = 68 (correct)
132 -68 = 64 surplus
