A customer enrolled in a 1 year product purchase plan that cost $60 per month after 6 months the customer received a monthly discount of 20% what is the total amount the customers will pay for the 1 year plan ?

Cost 6 months = 6 * 60 = $360

After that each month is reduced by 20%
20% of 60 = (20 / 100) * 60 = 12
New price = 60 - 12= 48

6 Months at 48 per month = 288

Total Cost = 360 + 288 = 648
