Question

There are seven cats in my neighborhood, with an average of 41 whiskers each. If one of the cats has 17 whiskers, how many whiskers does each of the other cats have on average?

Answer 1

45

Explanation:

Solution #1

Let W be the total number of whiskers among all seven cats. Then we know that W/7 = 41, so W = 7 ∙ 41 = 287. If we remove the cat with 17 whiskers from consideration, then we have six other cats with a total of 287 - 17 = 270 whiskers, so their average number of whiskers is 270/6 = 45.

Solution #2

We can use the concept of "balancing". The cat with 17 whiskers has 24 fewer whiskers than average (since 41 - 17 = 24). Therefore, the other six cats must have a total of 24 more whiskers than six average cats. That's an average of 24/6 = 4 extra whiskers per cat, so these six cats have an average of 45 whiskers each.

Answer 2

about 37.57

Explanation:

basically multiply the original number by 6 then add 17 then divide it by seven. I think. dont hate me if im wrong. im kinda dumb
