A camp counselor took a survey of the 25 campers he had in his group to determine which activity the campers were most interested in. He found that 7 were interested in ziplining, 6 were interested in fishing, 9 were interested in horseback riding, and 3 were interested in a ropes course. If there are 150 campers, what is a reasonable estimate that the camper will be interested in ziplining?

To find a reasonable estimate, we can use proportions. We know that there are 25 campers in the group who were surveyed, and 7 of them were interested in ziplining.
So, the proportion of campers interested in ziplining is 7/25.
To find the estimate for the whole camp, we can set up a proportion:
7/25 = x/150
Cross multiplying, we get:
25x = 7 * 150
25x = 1050
Dividing both sides by 25, we find:
x = 42
Therefore, a reasonable estimate is that 42 campers will be interested in ziplining.
The answer is 42.
