N(t)= 15000 e^(.07 t)
let's assume 2005 is 0 and 2013 will be 8 years.
n(8)=15000e^(.07*8) = 26260 growth of foxes.
1/10x200
= 1/10x200/1
= 200/10
=20
the answer is 20
if u dont understand, 1/10 means a part of 200 that is divided by 10 which means the number x10 =200. So if u dont understand, you can check answer this way: n*10=200
200/10=n
n= 20
C(3) = -0.09(3)² + 3.5(3) + 8
= -0.09 * 9 + 10.5 + 8
= -0.81 + 18.5
= 17.69 parts per million
