Step 1: Calculate the unit price for Regular Size Detergent

To find the unit price of the Regular Size Detergent, we will divide its price by the number of ounces in the package. The given price for Regular Size Detergent is $8.64, and it comes in a 96-ounce package. So, the calculation for the unit price is: Unit Price (Regular Size) = $\frac{Price}{Size}$ = $\frac{8.64}{96}$

Step 2: Calculate the unit price for Family Size Detergent

To find the unit price of the Family Size Detergent, we will divide its price by the number of ounces in the package. The given price for Family Size Detergent is $10.24, and it comes in a 128-ounce package. So, the calculation for the unit price is: Unit Price (Family Size) = $\frac{Price}{Size}$ = $\frac{10.24}{128}$

Step 3: Compare unit prices

Now that we have calculated the unit prices for both detergent packages, we will compare them to see which is the best buy. The detergent with the lowest unit price is the better buy.

Step 4: Determine the best buy

Calculate and compare the unit prices from Step 1 and Step 2: Unit Price (Regular Size) = $\frac{8.64}{96}$ = \$0.09 per ounce Unit Price (Family Size) = $\frac{10.24}{128}$ = \$0.08 per ounce Since the unit price of Family Size Detergent is lower than that of Regular Size Detergent, the best buy in this case is the Family Size Detergent.
