Answer:
A. $1500
Step-by-step explanation:
We need to find the countertop area, so let's calculate the areas of the rectangles that the problem broke the countertop into:
1. "1 rectangle has a base of 70 inches and height of 20 inches"
The area of a rectangle is denoted by: A = bh, where b is the base and h is the height. Here, b = 70 and h = 20, so the area is: A = 70 * 20 = 1400 inches squared
2. "The other rectangle has a base of 20 inches and height of 30 inches"
Again, use A = bh: b = 20 and h = 30, so A = 20 * 30 = 600 inches squared
Add up these two areas: 1400 + 600 = 2000 inches squared.
The problem says that the cost is $0.75 per square inch, so multiply this by 2000 to get the total cost of 2000 square inches:
2000 * 0.75 = $1500
Thus, the answer is A.
Hope this helps!
