Bill's Appliance Store offers the following credit terms: "The finance charge is based upon the net balance if payment is made within $25$ days of the billing date. If payment is made after $25$ days, then the finance charge is based on the previous balance. Net balance equals previous balance less payments, returns and credits. In either case, the monthly interest rate is $1\mathrm{.}25\%$ on the first $$750$ of the net balance and $0\mathrm{.}75\%$ on any amount over $$750."$

Compute the net balance, the finance charge, and the new balance for the customer shown below. Assume that the payment was made within the $25-$day period.
