Question

The population growth per year for a newly discovered island is represented by the following, P(1) = 100(1.3). What is the percent rate of growth per year?

Answer 1

The percent rate of growth per year is 30%.

Step-by-step explanation:

The percent rate of growth per year can be calculated using the formula:

r = (P(1) - P(0))/P(0)

where P(1) is the population at time 1 and P(0) is the population at time 0.

In this case, P(1) = 100(1.3) = 130 and P(0) = 100. Substituting these values into the formula:

r = (130 - 100)/100 = 0.3

The percent rate of growth per year is 0.3 or 30%.
