You need to find the percentage difference between total amount paid and the original price.
Total amount paid = deposit + total installments.
Total amount paid = 20% X 4299 (deposit) + 155 x 24 (total installments)
Total amount paid - 4299 = difference
Difference / original price X 100% = simple interest
