To find the best buy on spaghetti sauce, we need to compare the prices of each brand after taking into account the coupons.
For brand X, we can subtract the coupon amount of $0.75 from the original price of $3.89. This gives us a discounted price of $3.89 - $0.75 = $3.14 for 28 ounces.
For brand Y, similarly, we can subtract the coupon amount of $0.25 from the original price of $1.89. This gives us a discounted price of $1.89 - $0.25 = $1.64 for 18 ounces.
Brand Z doesn't have a coupon, so the price remains at $1.29 for 13 ounces.
To compare the prices, we can calculate the cost per ounce for each brand.
For brand X, the cost per ounce is $3.14 / 28 = $0.112 per ounce.
For brand Y, the cost per ounce is $1.64 / 18 = $0.091 per ounce.
For brand Z, the cost per ounce is $1.29 / 13 = $0.099 per ounce.
Based on the cost per ounce, brand Y is the best buy, as it has the lowest cost per ounce at $0.091.
