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
