The amount payed each month by Andy is £ 504
Solution:
Given that, Andy is buying a car.
He negotiated a 7 percent decrease on a 6500 car.
Then, amount to be paid = 6500 – 7% of 6500

He will pay the full balance in 12 equal monthly payments.
We have to calculate the amount paid each month

Hence, Andy has to pay £ 504 approximately each month.
