Answer:
£75.60
Explanation:
If Mr Jackson pays the full amount within seven days, he will receive a 5% discount on the original price of £840.
5% of £840 is (5/100)*£840 = £42
So if Mr Jackson pays within seven days, he will only have to pay £840 - £42 = £798.
If he chooses to pay by direct debit, he will have to pay 8% more than the original price of £840.
8% of £840 is (8/100)*£840 = £67.20
So if he chooses to pay by direct debit, he will have to pay £840 + £67.20 = £907.20 in total.
This amount will be divided into 12 equal monthly payments, so each monthly payment will be:
£907.20 / 12 = £75.60
Therefore, if Mr Jackson chooses to pay by direct debit, his monthly payment will be £75.60.
