Question

Suppose that 21 inches of wire costs 84 cents.

At the same rate, how much in cents) will 47 inches of wire cost?

Answer 1

44 cents

Explanation:

First we need to find out how much per inch so do 84 divided by 21 which is 4 then get the closest to the number 47 which is 44 so 4x11=44 cents I'm not sure if it's right tho
