Answer:
her bank statement will show that she has $144 less than her checkbook balance
Step-by-step explanation:
let the amount of money in the bank before writing the check be x
after writing the check for $72, because she accidentally recorded this as a credit, here checkbook will reflect a balance of :$(x + 72)
However, the bank correctly records the debit of the $72, resulting a balance of: $(x-72)
Hence compared to her checkbook, the bank records will show an amount difference of :
(x-72) - (x + 72)
= x - 72 -x -72
= -144
i.e her bank statement will show that she has $144 less than her checkbook balance
