Answer:
The cost of carpeting is $1250 ⇒ answer B
Explanation:
* Lets explain how to solve the problem
- Alex wants wall-to-wall carpeting in his office
- The measures of it is 25 feet by 18 feet
- The cost of the carpet is $25 per square yard
* At first lets change the measures of carpeting from feet to yard
∵ 1 yard = 3 feet ⇒ divide both sides by 3
∴ 1 foot = 1/3 yard
∵ The dimensions of carpeting are 25 feet and 18 feet
∴ 25 × 1/3 = 25/3 yards
∴ 18 × 1/3 = 6 yards
∴ The dimensions of carpeting are 25/3 yards and 6 yards
* Lets find the area of carpeting to calculate its cost
∵ The Area carpeting is the product of the dimensions
∴ Area = 25/3 × 6 = 50 yard²
∵ The cost of 1 square yard of carpeting is $25
∴ The cost of the carpet = 50 × 25 = 1250
* The cost of carpeting is $1250
