75,000 divided by 150, is 500, meaning they allow 500 people per acre. 500 times 145 is 72,500, meaning the capacity for a park your size should be 72,500 people.
Okay, so FIRST you would subtract 215 - 155, which is 60, and THEN
divide it by 215, so 60 divided by 215 = 0.27, and rounded that is 0.28,
then you move the decimal two places to the right to make it a
percentage so your answer would be A., 28%
I hope I helped! =D
To solve this you would need to make all fractions like fractions and when you do this you should get 1 1/15
