Question

Suppose that 14 inches of wire costs 70 cents at the same rate how much (in cents) will 41 inches of wire cost?

Answer 1

41 inches of wire costs $2.05

41 x .05

Explanation:

If 14 inches of wire costs 70 cents, we can solve for cost per inch.

If we divide both numbers by 2 we get

7 inches of wire costs 35 cents

Divide both by 5 and we get

1 inch of wire costs 5 cents
