Final answer:

To determine how many campers could be supervised by 9 counselors, set up a proportion and solve for the unknown value using cross multiplication.

Step-by-step explanation:

To determine how many campers could be supervised by 9 counselors, we can set up a proportion based on the given rate. Since 1 counselor is needed to supervise 8 campers, the ratio can be written as 1:8. To find the number of campers when there are 9 counselors, we can use the following proportion: 1 counselor / 8 campers = 9 counselors / x campers. Cross multiplying, we get 1x = 8 * 9, which simplifies to x = 72. Therefore, with 9 counselors, you could have 72 campers.
