22 counselors

Explanation:

1. Ratio of campers to counselors in june:

number of campers: 325

number of counselors: 26

Ratio = number of campers / number of counselors

Ratio = 325 campers / 26 counselors

2. Ratio of campers to counselors in july:

number of campers = 325 - 265 + 215 = 275

number of counselors = x (unknown)

Ratio = 275 campers / x

3. Equivalent ratios:

325 campers / 26 counselors = 275 campers / x

Solve for x:

x = (26counselors/325campers) * 275campers = 22 counselors ← answer
