The answer is actually 80 degrees, I just took the test.
S(8)=3500(1+(.047/4))^32
S(8)=$5086.40 in the account after 8 years.
a)The relative growth rate is .25, or 25%
b)at t=0, the population is 955e^.25(0)=955
c)at t=5; the population is 955*e^.25(5)=955*3.49=3333.28 bacterium.
0.93 = 0.9
0.18 = 0.2
0.9 + 0.2 = 1.1
