A business owner wants to have a rectangular parking lot resurfaced. The lot is 93 feet long by 58 feet wide. Basesd on a cost of $2.47 per square foot, the owner incorrectly estimated that it would cost $12,000 to have the lot resurfaced. Which could be used to get an estimate that is closest to the actual cost of resurfacing the parking lot?
Choices:
100 x 60 x 1.5
100 x 60 x 2
90 x 60 x 2
90 x 60 x 1.5
I say A
Not 2.47, 1.47
I would say c
A, if the cost is 1.47
I would use C.
I think its D
Wow there are a lot of different answers I will just ask some of you fellow students to check your answers again.
umm the answer is de because you estimate 93 to the nearest tenth which is 90 and then round 58 to the nearest tenth which is 60 and then estimate 1.47 which is 1.5 and then you multiply all of them together and then thats the estimate of how much he has to pay
To find the actual cost of resurfacing the parking lot, we need to calculate the area of the lot and multiply it by the cost per square foot.
The area of a rectangle can be found by multiplying its length by its width. In this case, the length of the lot is 93 feet and the width is 58 feet.
Area = length x width = 93 feet x 58 feet = 5394 square feet
Now, we can multiply the area by the cost per square foot to get the actual cost:
Actual cost = Area x cost per square foot = 5394 square feet x $2.47/square foot = $13,322.18
Out of the given choices, we can calculate the volume of each option (length x width x height) and see which one results in an estimate closest to the actual cost of $13,322.18.
Let's calculate the options:
1) 100 x 60 x 1.5 = 9000 cubic feet
2) 100 x 60 x 2 = 12000 cubic feet
3) 90 x 60 x 2 = 10800 cubic feet
4) 90 x 60 x 1.5 = 8100 cubic feet
Based on the actual cost of $13,322.18, option 2) with a volume of 12000 cubic feet would provide an estimate that is closest to the actual cost of resurfacing the parking lot.
