Answer:
about $2546.88
Explanation:
You would multiply 15x20 to find the area, which is 300 sq ft. Then, you would find the cost per square foot by dividing 2275/300 which is 7.58 rounded to the nearest hundredth. Now that you have the cost per square foot, you find the area of 12x28 which is 336. Then, you just multiply 336(7.58) which is equal to $2546.88
