    Suppose that 17 inches of wire costs 51 cents at the same rate, how many inches of wire can be bought for 42 cents?

    Set up a proportion of inches of wire to cost, were w equals the inches of wire at 42 cents. We have:
    17/51 = w/42

    Type this proportion into our search engine, we get:
    w = 14
