Acount went up from 450 to 600. what was the approximate percent increase?
the percent increase was approximately 33%.
the percent increase was approximately 75%.
the percent increase was approximately 133%.
the percent increase was approximately 300%.

A count went up from 450 to 600.The percentage increase was approximately 33%.

Solution:

Given that a count went up from 450 to 600

Initial value of count = 450

Final value of count = 600

We need to calculate percentage increase in count

Percentage increase is calculated by dividing the difference of final value of count and initial value of count by initial value and multiplied by 100

On substituting the values, we get

On simplifying,

Hence the percentage increase was approximately 33%.

answer: all we have to find the fraction of students who preferred green and go from there.

subtracting blue and red out of the all students,

1- (1/8+1/4)

1- 3/8

5/8 is the remaining students, in order to find 3/5 of the remaining students, we multiply by 3/5

5/8(2/5) = 3/8

3/8 preferred green, which was 15 students. in order to get 100% of the whole   population (1), we multiply by 8/3:

15(8/3) = 40

40 students were surveyed in total.
