Final answer:
The amount received as payment in full on June 23 is $685.
Step-by-step explanation:
To find the amount received as payment in full, we need to calculate the net amount due after considering the terms of the credit sale and the return granted.
- Subtract the discount from the original amount to find the net amount due: $750 - (2% of $750) = $735
- Subtract the return from the net amount due: $735 - $50 = $685
Therefore, the amount received as payment in full on June 23 is: (c) $685.
