Question

Suppose that 16 inches of wire costs 48 cents.

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

Answer 1

let’s divide 48 by 16 to see how many cents per inch of wire. 48/16=3 so it costs 3 cents per inch of wire. now all we have to do is multiply 47 by 3, and you will get 141 cents, or $1.41.
