Answer:
$2800
Step-by-step explanation:
First of all, the order received from Tinley High School has not been delivered by the end of November ,hence the value of the order is irrelevant for the purpose of calculating net accounts receivable at the end of November.
However, out of the goods of $3120 sold to Palos Middle School,$320 worth has been returned as defective,leaving a balance of $2800($3120-$320).
For Palos to be entitled to the discount of 2% they should have made payment by 24th November,which never happened,as a result the accounts receivable stay at $2800
