Suppose that 16 inches of wire costs 64 cents.At the same rate, how much (in cents) will 13 inches of wire cost?
Question
Suppose that 16 inches of wire costs 64 cents.At the same rate, how much (in cents) will 13 inches of wire cost?
Solution
Step 1: First, we need to find the cost of wire per inch. We know that 16 inches of wire costs 64 cents. So, we divide the total cost by the total length of the wire to find the cost per inch.
64 cents / 16 inches = 4 cents per inch
Step 2: Now that we know the cost per inch, we can find out how much 13 inches of wire will cost. We multiply the cost per inch by the number of inches.
4 cents per inch * 13 inches = 52 cents
So, 13 inches of wire will cost 52 cents.
