Question

You are coating your rectangular driveway with blacktop sealer. The driveway is 60 feet long and 10 feet wide. One can of sealer costs 15 dollar and covers 200 square feet. a. Determine the area of your driveway. b. Determine how many cans of blacktop sealer you need. c. Determine the cost of sealing the driveway.

Short answer

Answer: The total cost of sealing the driveway is 45 dollars.

Step-by-step solution

Calculate the area of the driveway

To calculate the area of the driveway, use the formula for the area of a rectangle: Area = Length × Width In this case, the length is 60 feet, and the width is 10 feet. So, the area is: Area = 60 feet × 10 feet = 600 square feet

Determine how many cans of blacktop sealer you need

One can of sealer covers 200 square feet. To determine how many cans of sealer you need, divide the total area by the coverage per can: Number of cans = Area ÷ Coverage per can Number of cans = 600 square feet ÷ 200 square feet/can = 3 cans Since you can't buy a fraction of a can, you have to round up to the nearest whole number of cans. In this case, you need 3 cans of sealer to cover the entire driveway.

Determine the cost of sealing the driveway

The cost of one can of blacktop sealer is 15 dollars. To determine the total cost, multiply the number of cans needed by the cost per can: Total cost = Number of cans × Cost per can Total cost = 3 cans × 15 dollars/can = 45 dollars So, the total cost of sealing the driveway is 45 dollars.
