An invoice dated 4/18/xx received by ralph's supply indicated a balance of $7,000. this balance included a freight charge of $500. terms of the bill were 4/10, 3/30, n/60. assuming ralph pays off the bill on april 30, he pays:

The total amount would be $6,805

Explanation:

The computation of the amount paid is shown below:

invoice amount = $6,500  ($7000 - $500)

Less - discount ($6,500 × 3%) = ($195)

Net balance = $6,305

Add - freight charges = $500

Total amount paid = $6,805

In invoice amount, the freight charges are added, so first, we have to deduct the freight charges to get the actual value than we deduct the discount of 3% since the payment was made on April 30.  

From 18 April to April 30, 13 days are there so we take a 3% discount rate since the payment was made within 30 days.  

And, after that, the freight charges are added back to get the total amount which would be paid.
