Question

Suppose that 15 inches of wire costs 75 cents.

At the same rate, how much (in cents) will 9 inches of wire cost?

Answer 1

Answer:45 cents for 9 inches of wire

Explanation:

Per every 5 incheses is 0.25 cents 0.75/15=$0.25 and then taking 0.25/5=$0.05 cents. So 1 inch costs 0.05 cents. So multiply 0.05×9=$0.45 cents. 45 cents

Answer 2

Answer: 45 cents.

Step-by-step explanation: We can find the cost per inch of wire by dividing the total cost by the total length of wire:

75 cents / 15 inches = 5 cents/inch

Now that we know the cost per inch, we can find the cost of 9 inches of wire by multiplying the cost per inch by 9:

5 cents/inch * 9 inches = 45 cents.
