please help! The population of randolph grew from 300 to 900 since the last census. What was the percent of?

Question

increase? How to solve?

Answer 1

Let's work it through together.

100% means the whole amount, so if Randolph had 300 people, then a 100% increase would be 300 people.

The way to figure out how much Randolph grew by is to divide the new population by the old population, then subtract 1 (the base amount).

In this case, 900/300 = 3, so Randolph is now three times larger than it used to be, and has added twice as many people, or 200%.

Answer 2

R1 == Randolph's initial census (300)
R2 == Randolph's second census (900)
G == The number of times Randolph's population Grew
G == ( R2 - R1 ) / R1
% of increase = G * 100

R2 - R1 == 600
G = 600 / 300 = 2
G * 100 = % of increase = 2 * 100 = 200

Answer 3

200%

900 - 300 = amount of increase (600)
600 / 300 * 100 = % of increase

Answer 4

percentage increase is 200%...
300 was the population...300 is equal to 100% therefore another 300 people takes your population to 600, and inturn another 300 people takes the population to 900 which is 200%
