Answer to Problem 18SGR

A twelve pack of juice boxes costs $\$6.59$ is better to buy.

Explanation of Solution

Given information:An eight pack of juice boxes costs $\$4.79$ and a twelve pack of juice boxes costs $\$6.59$

Calculation:

Case1: An eight pack of juice boxes costs $\$4.79$

Now, cost of one juice box is calculated as follows:

  $\begin{array}{l}=\frac{4.79}{8}\\ =0.59875\end{array}$

Thus, cost of one juice pack is $\$0.59875$

Case2: A twelve pack of juice boxes costs $\$6.59$

Now, cost of one juice box is calculated as follows:

  $\begin{array}{l}=\frac{6.59}{12}\\ =0.5491\end{array}$

Thus, cost of one juice pack is $\$0.5491$

Since cost of one juice pack in case2 is less, thus it is better to buy.
