Question

1) The population of Leafy Lake starts at 3,000 and grows by 25% every year. What will the population be in 6 years?

how do I solve it

Answer 1

X/3,000 = 25/100
100x = 3,000x25
100x = 75,000
100x/100 = 75,000/100
X = 750

750x6 = 4,500
Every year the population goes up by 750, in 6 years the population would be 4,500 people.

Answer 2

Explanation:

Rate of increase = r = 25%

n = number of years = 6

P = Current population = 3000

Population after n years =
`P*(1 + (r)/(100))^(n)`

`= 3000 * (1 +0.25)^(6)\\\\= 3000 * (1.25)^(6)\\\\= 3000 * 3.8\\\\= 11400=`
