Answer to Problem 3.5P

The number of candy bar and soft pretzels sold are $131$ and $100$ respectively.

Explanation of Solution

Given information:

The total amount raises is $\$62.75$ , the profit made in each candy bar is $\$0.25$ and the profit made in each pretzel is $\$0.30$ .

The equation for the number of candy bar and soft pretzels sold is,

  $0.25x+0.30y=62.75$

By using guess and check strategy,

  $\begin{array}{l}x=131\\ y=100\end{array}$

Thus, the number of candy bar and soft pretzels sold are $131$ and $100$ respectively.
