Question

what would be the ratio of the number of cans to the price at Super Saver and Price Buster if a coupon for $1 off the total purchase is used?

Answer 1

For Super Saver, the original price is 4 cans for $10 so with the coupon it would be 4 cans for $9. If you need price per can you can set up a proportion so 4x=9. This gives you $2.25 per 1 can.

For Price Buster, the new price is 3 cans for $8. You can also use a proportion for this one. This time it would be 3x=8. So about $2.67 per 1 can.
