Population Growth

The initial population of gibbons is 10. The average increase per month is 1.25. Assuming a linear model, calculate the number of gibbons in 10 years time.

Solution


Hello, Kerry! I would be more that happy to help you with this problem. The standard form for a linear model can be f(x) = 1.25x + 10, where x is the number of months. Since there are 120 months in 10 years, you can have the following linear model:

f(120) = 1.25(120) + 10

f(120) = 150 + 10

f(120) = 160
