Payment without the registration fee = 1300 - 50 = 1250 tk Now, Total Cost of first 3 days = 3*50 = 150 tk Total Cost of next 5 days = 5*100 = 500 tk Thus, Total cost of first 8 days = 500+150 = 650 tk We can see that the person surely stayed at least 8 days. Remaider of the payment is = (1250-650) = 600 tk Now, Afterward each day costs 300 tk. Thus, with the remainder of money person could stay = (600/300) days = 2 days Thus, Total days of the person's stay = 8 + 2 = 10Related questions
