Answer:
Each monthly payment is of £560.
Explanation:
Sue buys a car costing £8000 plus 20% VAT?
She has to pay:
8000 plus 20% of tax. So

She pays £4000 deposit and then chooses to pay the balance in ten equal monthly payments.
4000 deposit, and then 9600 - 4000 = 5600 divided in ten equal monthly payments.
5600/10 = 560
Each monthly payment is of £560.
