# Problem of the Week Problem A and Solution Zoo Field Trip

## Problem

The following list gives the fees at the POTW Children’s Zoo.

Yesterday the POTW Children’s Zoo had $$24$$ visitors. One quarter of the visitors went to pet the llamas, one half of the visitors used the zip line, and $$5$$ visitors had the zoo lunch. How much money did the POTW Children’s Zoo make yesterday?

## Solution

We can determine the amount of money that the POTW Children’s Zoo made yesterday by adding the total amounts for each type of fee.

Entry fees would be $$24 \times \8 = \192$$.

Since one quarter of $$24$$ is $$24 \div 4 = 6$$, then the extra fees for petting the llamas would total $$6 \times \5 = \30$$.

Since one half of $$24$$ is $$24 \div 2 = 12$$, then the extra fees for the zip line would total $$12 \times \4 = \48$$.

The money made for the $$5$$ lunches would total $$5 \times \7 = \35$$.

Altogether, the POTW Children’s Zoo made $$\192 + \30 + \48 + \35 = \305$$ yesterday.
