Final answer:
Wanda did not spend any additional money for the finish paint.
Step-by-step explanation:
To find out how much more Wanda spent for the finish paint, we need to calculate the total cost of the paint she used for the first coat and subtract it from the total cost of the finish paint. First, let's calculate the number of cans of paint she used for the first coat by dividing the surface area of the house by the coverage area of each can: 2800 square feet / 400 square feet/can = 7 cans. Since each can of paint covers 400 square feet and Wanda used 7 cans for the first coat, the total area covered is 7 cans * 400 square feet/can = 2800 square feet. The total cost of the first coat of paint is the coverage area multiplied by the cost per gallon, divided by the coverage area per can: (2800 square feet * $22.25 per gallon) / 400 square feet = $154.7.
Next, we calculate the number of cans of finish paint Wanda used by dividing the remaining surface area of the house by the coverage area of each can: (2800 square feet - 2800 square feet) / 400 square feet/can = 0 cans. Since Wanda did not use any cans of finish paint, the total cost of the finish paint is $0. Finally, we subtract the total cost of the first coat of paint from the total cost of the finish paint: $0 - $154.7 = -$154.7. Therefore, Wanda did not spend any additional money for the finish paint. The correct answer is E. $33.25.
