To find the unit price for each brand after applying the coupon, we need to subtract the amount of the coupon from the original price and then divide by the number of ounces.
For Brand G, the original price is $1.99 for 9 ounces. Since we have a coupon for 60 cents off, the new price would be $1.99 - $0.60 = $1.39. So the unit price for Brand G after applying the coupon is $1.39/9 ounces = $0.1544 per ounce.
For Brand K, the original price is $3.69 for 17.2 ounces. There is no coupon for this brand, so the unit price remains the same: $3.69/17.2 ounces = $0.2148 per ounce.
For Brand P, the original price is $3.39 for 11.8 ounces. Since we have a coupon for 50 cents off, the new price would be $3.39 - $0.50 = $2.89. So the unit price for Brand P after applying the coupon is $2.89/11.8 ounces = $0.2450 per ounce.
To determine which brand is the best buy, we compare the unit prices after applying the coupons. The brand with the lowest unit price is the best buy. Comparing the unit prices we calculated, the best buy is:
A. Brand G (unit price: $0.1544 per ounce).
