Homework Help: Math

The population of termites and spiders in a certain house are growing exponentially. the house contains 100 termites the day you move in. After 4 days, the house contains 200 termites. Three days after moving in, there are two times as many termites as spiders. Eight days after moving in, there were four times as many termites as spiders/ Hows long in days does it take the population of spiders to triple?



What I done so far.
TERMITES
y(not)=100
t=4
y=200
200=100b^4
b=2^(1/4)
T(t)=100(1.189207)^t

for the spiders.S(t).. i tried plugging t=3 and t=8and divided by two and four to the T(x) equation.... and for two numbers 84.089 and 99.99..... but I think Im doing it wrong

or is it
T(t) = 2(S(t))?
