Question

A tile company adds 10% spoilage when estimating floors. We have a floor that is

75 feet by 68 feet and we want to know about what the company is going to buy to
account for the spoilage. We estimate the dimensions of the room to the nearest tens
and then the 10% spoilage.

Answer 1

First, we need to calculate the total area of the floor without the spoilage. To do this, we'll multiply the length of the floor (75 feet) by the width of the floor (68 feet):
75 feet x 68 feet = 5050 square feet

Next, we need to calculate the spoilage by multiplying the total area by 10% (or 0.1). To do this:
5050 square feet x 0.1 = 505 square feet

So the spoilage is 505 square feet.

To account for this spoilage, the company will need to purchase an additional 505 square feet of tile.

Now since we need to estimate the dimensions of the room to the nearest tens, we can round the width and length to 70 and 80 respectively.

So the final estimate of the floor area will be 70 feet x 80 feet = 5600 square feet

So the company will have to purchase 5600 square feet of tile to cover the floor and account for the spoilage.
