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 cents

Step-by-step 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

Answer 2

195¢

Step-by-step explanation:

1 inch of the wire costs

`(85)/(17)` cents

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

`(85)/(17) * 39 = 195`
