Apply 9. Aubrey is painting a mural of an ocean scene. The. triangular sail on a sailboat has a base of 6 feet anda height of 4 feet. Aubrey will paint the sail using a special white paint. A container of this paint covers 10 square feet and costs \( \$ 6.79 \) per container. How much will Aubrey spend on the white paint?

To find out how much Aubrey will spend on the white paint, we first need to calculate the area of the triangular sail. The formula for the area of a triangle is: \[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \] Plugging in the values: \[ \text{Area} = \frac{1}{2} \times 6 \, \text{feet} \times 4 \, \text{feet} = 12 \, \text{square feet} \] Next, we need to determine how many containers of paint Aubrey will need. Since each container covers 10 square feet, Aubrey will need: \[ \frac{12 \, \text{square feet}}{10 \, \text{square feet/container}} = 1.2 \, \text{containers} \] Since paint is sold by the container, Aubrey will need to round up to 2 containers. Now, let's calculate the total cost: \[ 2 \, \text{containers} \times \$6.79/\text{container} = \$13.58 \] So, Aubrey will spend **\$13.58** on the white paint.
