Question

In June, a camp has 325 campers and 26 counselors. In July, 265 campers leave and 215 new campers arrive. How many counselors does the camp need in July to keep an equivalent ratio of campers to counselors?

Answer 1

`\boxed{22}.`

Explanation:

In June, the camp had 325 campers and 26 counselors, for a ratio of 325/26=<<325/26=12.5>>12.5 campers per counselor.

In July, there are 325-265=<<325-265=60>>60 remaining campers from June, and 215 new campers arrive, for a total of 60+215=<<60+215=275>>275 campers in July.

To maintain the same ratio of campers to counselors as in June, the camp would need 275/12.5=<<275/12.5=22>>22 counselors in July.
