Question

directrix · Answer

If 4% of the 125 deer die each month, then 96% or .96 of the deer are present at the end of the month.

d = 125*( .96)^n should be the number of deer still alive at the end of n months.

directrix · Answer

Let's test it.

directrix · Answer

Testing that, if n = 2, how many deer will be present at the end of 2 months?

directrix · Answer

125 - .04*125 = 120 deer after 1 month.

120 - .04*120 = 115.2 deer after 2 montha


Using the formula:

d = 125 *( 6)^n.9 where n = yields

125 *( .96)^2 =15.2

directrix · Answer

d = 125*( .96)^n   is correct.
