Question

A tile store charges $385 to install 70 square feet of tile. Assuming they charge the same rate per square foot regardless of the amount of tile installed, how much would they charge you to install 1100 square feet of tile?

a. $1575
b. $2200
c. $550
d. $7700

Answer 1

$385/70 ft² = x/1,100 ft²

70x = 423,500

x = $6,050

None of those choices are correct.

Answer 2

To find the cost to install 1100 square feet of tile, the rate of $385 for 70 square feet was used to calculate a rate of $5.50 per square foot, leading to a total cost of $6050.

Step-by-step explanation:

The question asks us to calculate the cost of installing 1100 square feet of tile based on a given rate of $385 for 70 square feet. First, we should find the cost per square foot by dividing the total cost by the total square feet provided:

1. Determine the rate: $385 ÷ 70 square feet = $5.50 per square foot.
2. Calculate the cost to install 1100 square feet: 1100 square feet × $5.50 per square foot.
3. Perform the multiplication to find the total cost: 1100 × $5.50 = $6050.

Therefore, the tile store would charge $6050 to install 1100 square feet of tile.
