Suppose that 12 inches of wire costs 60 cents. at the same rate, how much (in cents) will 27 inches of wire cost?

The 12 inches wire costs 60 cents, so the cost of 1 inch of wire is

Rate = 60/12 = 5 cents

So the cost of 1 inch of wire which is the rate is 5 cents.

Now we have to find the cost (in cents) of 27 inches wire.

We know the cost of 1 inch of wire is 5 cents so the cost of 27 inches of wire is

= Total inches of wire * Price of 1 inch of wire

= 27 * 5

= 135

The cost of 27 inches of wire is 135 cents

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
