Answer 1

C) 44 cabins

Explanation

Step 1

find the number of students that will be spending the night in cabins.

Let

total=472

students will be returning=120

students will be spending the nigth in cabins=x

then

$\begin{gathered} x+120=472 \\ \text{subtract 120 in both sides} \\ x+120-120=472-120 \\ x=352 \end{gathered}$

it means 352 students will be spending the night in cabins

Step 2

find the number of cabins

$\begin{gathered} 1\text{ cabin }\Rightarrow\text{8 people} \\ y\text{ cabin}\Rightarrow352 \\ \frac{1}{8}=\frac{y}{352} \\ y=\frac{352}{8} \\ y=44 \end{gathered}$

so, the answer is 44 cabins
