Sam wants to cover his garden patio with brick tiles. His patio measures 15 feet by 20 feet. Each brick is 1 foot x 1 foot and costs $2. How much money will Sam spend if he buys exactly enough tiles to cover his patio?
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
