Rate of Growth is: 300

a) Use your equation in part b(equations: P = 300t + 1750) to approximate how many years it will take the population to reach 7000.

b) Graph this function in MS Excel by plotting the points found in your chart in part a. Label your axes with time on the x-axis and population on the y-axis.

#### Solution Preview

a) When P = 7000, substitute 7000 for P to the equation,

300t + 1750 = 7000

300t = 7000 - 1750

300t = 5250

t = 5250 / 300

t = 17.5

so it will take 17 and half years for ...

#### Solution Summary

The solution shows how to calculate how many years it will take the population to reach 7000.
