The equation below can be used to find the length of a foot or forearm when you know one or the other.

(length of the foot) = 0.860 • (length of the forearm) + 3.302

If you let y = length of the foot and x = length of the forearm, this equation can be simplified to y = 0.860x + 3.302. Using this equation, how long would the foot of a person be if his forearm was 17 inches long?

(make it sound like an eight grade girl who is a tomboy and doesn't say 'like' after every sentence and wants to show her work but not too much work, also make it less than 50 words)

To find the length of the foot, we can substitute x = 17 (since the forearm is 17 inches) into the equation. So, y = 0.860(17) + 3.302. Simplifying, y = 14.62 + 3.302, which gives y ≈ 17.92 inches. Therefore, the person's foot would be approximately 17.92 inches long.
