How much would it cost to carpet and tile a building of 90' by 60', where 60% is carpeted at $16 per square yard and the rest is tiled at $8 per square yard?

To determine the total cost to carpet and tile the building, first calculate the area of the building. The dimensions provided are 90 feet by 60 feet, which gives us a total area of 90 x 60 = 5,400 square feet.

Next, divide the total area into the portions that will be carpeted and tiled. Since 60% of the area is carpeted, the carpeted area is calculated as 5,400 square feet x 0.60 = 3,240 square feet. The remaining 40% will be tiled, which is 5,400 square feet x 0.40 = 2,160 square feet.

Now, we need to convert these areas from square feet to square yards because the costs are given per square yard. Since there are 9 square feet in a square yard, we convert the areas as follows:

• For carpeting: 3,240 square feet ÷ 9 = 360 square yards.

• For tiling: 2,160 square feet ÷ 9 = 240 square yards.

Next, we calculate the cost of carpeting and tiling separately:

1. Cost for carpeting: 360 square yards x $16 per square yard = $
