Question

Suppose that 17 inches of wire costs 85 cents.
At the same rate, how much (in cents) will 39 inches of wire cost?

Answer 1

Answer:

195¢

Step-by-step explanation:

1 inch of the wire costs

$\frac{85}{17}$ cents

So we just multiply by 39 to get the total cost.

$\frac{85}{17} * 39 = 195$

Answer 2

Answer: 195 cents

Explanation:

17 inches cost 85 cent

Means 1-inch will cost 85/17 = 5 cents

At the same rate 39 inches will cost 39×5= 195 cents
