The model N=10(4+3t)/1.25 describes the number of deer (N) in a park t years
after 40 deer are introduced into the region.
Approximately how long will it take the deep population to reach 224?
:
We can do it this way:
10() = 224
Divide both sides by 10
= 22.4
Multiply both sides by 1.25
4 + 3t = 1.25(22.4)
4 + 3t = 28
3t = 28 - 4
3t = 24
t =
t = 8 yrs

You can check this in the original equation
10() =
10() =
10() = 224
10(22.4) = 224
