Answer:
1) 20% change I think its an increase.
If needed I could try to answer the 2nd question but I am sure that I got the first one right.
Step-by-step explanation:
The solution for this problem is:
The population is 500 times bigger since 8000/24 = 500. The population after t days is computed by:P(t) = P₀·4^(t/49)
Solve for t: 8000 = 8·4^(t/49) 1000 = 4^(t/49) log₄(1000) = t/49t = 49log₄(1000) ≅ 244 days
25
X x 5 = 125
125/5=x
X=25
