Question

Find the unit price.Find which is the better buy (lower cost per ounce) by finding each unit 6) price rounded to three decimal places if necessary. Assume that different sizes of the same brand are being compared. Frozen orange juice: $11.86 for 18 ounces $7.80 for 12 ounces

Answer 1

To determine the better bargain of the two items, we shall calculate the unit price as follows;

$\begin{gathered} \text{For 18 ounces;} \\ \text{Unit price}=\frac{11.86}{18} \\ \text{Unit price}=0.6588 \\ \text{Rounded to 3 decimal places;} \\ \text{Unit price}=0.659 \end{gathered}$$\begin{gathered} \text{For 12 ounces;} \\ \text{Unit price}=\frac{7.80}{12} \\ \text{Unit price}=0.65 \end{gathered}$

The unit price for both categories are given. From our calculations, we can determine that $7.80 for 12 ounces is a better deal because, this costs less as compared to the other one. The difference is insignificant but nevertheless, there is a difference between $0.659 and $0.650

ANSWER:

The better buy is $7.80 for 12 ounces
