From the information given,
The price of the car is $5600. There is a tax rate of 4% on the car. This means that the amount of tax charged on the car is
4/100 x 5600 = 224
The total cost of the car is the sum of the tax and the inital price of the car. thus,
Total cost of car = 5600 + 224 = $5824
The down payment is 20%. This means that the amount paid as down payment is
20/100 x 5824 = 1164.8
total amount paid as loan = total cost - down payment = 5824 - 1164.8
total amount paid as loan = $4659.2
