Can somone help me with this math please?

Jones Advertising Agency received a $3,000 invoice dated June 8. Terms were 2/10, 1/15, n/60. On June 22 Jones Advertising sent a $1,600 partial payment. What credit should Jones Advertising receive? What is Jones' outstanding balance? Round to nearest cent.

The credit should be $1600.00 /the outstanding balance is $1400.00

It's a trick question. There's no discount available from most businesses since the account was not paid in full. In such case, the credit his account received is in-fact his payment amount. His account will be "credited' $1,600.00. His outstanding balance is $1,400.00. Now, however, if this creditor allows discounts on partial payments, Jones gets a 1% discount for the $1,600.00: 1% x 1600.00 = .01 x 1600.00 = $16.00. Jones account is credited $1616.00. His balance is $1384.00. Ask the teacher if the creditor gives discounts for partial payments.
