Answer:
For second period
Cash interest = $3,720,000 * 8% = $297,600
Interest expenses = 3,262,800 * 10% = $326,280
Discount = $326,280 - $297,600 = $28,680
For third period
Cash interest = $3,720,000 * 8% = $297,600
Interest expenses = $3,291,480 * 10% = $329,148
Discount = $329,148 - $297,600 = $31,548
