Answer 1

Answer: To determine which size is the better buy, we need to calculate the cost per ounce for each size, taking into account the coupon for the regular size.

For the regular size, the cost per ounce is:

$8.00 / 20 oz = $0.40 per oz

With the $1.00 coupon, the cost for the regular size becomes:

$8.00 - $1.00 = $7.00

So the cost per ounce for the regular size with the coupon is:

$7.00 / 20 oz = $0.35 per oz

For the economy size, the cost per ounce is:

$10.00 / 40 oz = $0.25 per oz

Therefore, the economy size is the better buy as it costs only $0.25 per oz compared to $0.35 per oz for the regular size with the coupon.
