Oliver sees this offer on cat food:
Normal price
65p per can
Special offer
3 cans for the price of 2
He buys 9 cans of cat food using the special offer.
How much cheaper is this than paying the normal price?
The answer is 225 because 65 x 9 is 585 but the special offer is you get 1 can off every 3 cans (you pay 3 for the price of 2) so your equation is now 65 x 6 which gets you 360 now you subtract 360 from 585 and get 225 your answer
