P=0.042
So the answer should be b.
12563 is the correct answer
First subtract the original high from the new high:
567 - 540 = 27 more vacuums sold.
Now divide the increase amount by the original high and multiply that by 100 to get the percentage:
27 / 540 = 0.05
0.05 * 100 = 5% Increase.
2you suppose to multiplie the lenghts to the base
I would say B but I can't see the question very well.
