Question

In a summer camp there are 4 counselors who are in charge of 32 campers. If the camp wants to have 80 campers, how many counselors will they need to keep the same ratio?

Answer 1

10 counselors.

Step-by-step explanation:

The present ratio of counselors to campers = 4 : 32

Let the number of counselors needed = x

Then, in order to keep the same ratio:

`(4)/(32)=(x)/(80)`

Next, solve for x:

`\begin{gathered} (1)/(8)=(x)/(80) \\ 8x=80 \\ x=(80)/(8) \\ x=10 \end{gathered}`

The summer camp will need 10 counselors to have 80 campers.
