Question

Suppose that 11 inches of wire costs 33 cents.

At the same rate, how much (in cents) will 46 inches of wire cost?

Answer 1

138 cents

Explanation:

We can solve this in a really fun way.... ratios!

The ratio of inches to cost is: 11:33

Notice anything?

Yep! We can simplify

1:3

1 inch is 3 cents

We need to find the cost of 46 inches, so we would multiply 46 by 3

46 * 3 = 138

So, 46 inches of wire costs 138 cents
