Question

The number of moose in Alaska at the start of year n is Pn

The number of moose in Alaska at the start of the following year is given by

Pn+1 = 1.04(Pn - G) where G is a constant



At the beginning of 2015, there were 200 000 moose in Alaska.

At the beginning of 2016, there were 200 720 moose in Alaska.


Work out how many moose there were in Alaska at the beginning of 2017

Answer 1

201469 moose in 2017

Explanation:

P(2017)= 1.04(200000-7000)

Answer 2

200 720 = 1.04(Pn - G)

Pn - G = 192 500

Pn = 192 500 + G

At the beginning of 2017, there were Pn = 192 500 + G moose in Alaska.
