During a creel survey on Knox Lake, if each angler averages 1.25 fish per trip, how many anglers need to be contacted to reach 100 fish?

To determine how many anglers need to be contacted to reach a total of 100 fish when each angler averages 1.25 fish per trip, you can use the following calculation:

First, consider the average number of fish caught per angler, which is 1.25. To find out how many anglers are required to reach a total catch of 100 fish, you can divide the total fish by the average catch per angler:

100 fish ÷ 1.25 fish/angler = 80 anglers.

This calculation shows that contacting 80 anglers would yield a total of 100 fish based on the average of 1.25 fish caught per angler. This aligns with the principle of averages in surveys, where understanding the data trends helps in projecting total outcomes based on averages.
