you have just received your monthly account statement from "Great stuff !!!", which is your favorite store. you immediately notice that there is a "late/no payment" fee of 25 and a charge for 100 on the account that you did not make. you also note that the payment you made of 100 on November 10,2013, is not shown on the statement either. The date of the mystery charge and the date that you made payment at the store are the same. you think that the clerk mistakenly entered your payment as a purchase. you still have the receipt from your payment on your account. the receipt is number "11-11-13-0235" which was initialed by a "JLK" your account number is GSC245-03.
