To find out how many inches of wire can be bought for 24 cents, we can set up a proportion using the information given. Let's use x to represent the number of inches of wire that can be bought for 24 cents:
12 inches of wire costs 36 cents
x inches of wire costs 24 cents
Using the proportion:
12 inches/36 cents = x inches/24 cents
To solve for x, we can cross-multiply:
12 * 24 = 36 * x
288 = 36x
Dividing both sides by 36:
288/36 = x
x = 8
Therefore, for 24 cents, you can buy 8 inches of wire.
Suppose that 12 inches of wire costs 36 cents.
At the same rate, how many inches of wire can be bought for 24 cents?
