Suppose that 19 inches of wire costs 76 cents.
At the same rate, how many inches of wire can be bought for 52 cents?

Answer 1

Answer:

13 inches of wire can be bought for 52 cents.

Step-by-step explanation:

→ We can use proportion to solve:

$\frac{19 \: inches}{76 \: cents} = \frac{x}{52 \: cents} \\ \\ \frac{76x}{76} = \frac{988}{76} \\ \\ x = 13$
