    The first thing you should do in this case is to take out the area of the patio and the area covered by each brick.

    Patio area = (15) * (20) = 300 ft ^ 2

    Area brick = (1) * (1) = 1ft ^ 2

    Then, to get the number of bricks we have:

    n = (Patio area) / (Area brick)

    n = (300) / (1)

    n = 300

    Therefore, 300 bricks are needed. This means that the total cost is

    total cost = (2) * (300) = 600 $

    answer

    Sam will spend if he buys exactly enough tiles to cover his patio $ 600
