Let the original amount be A. Double that would be 2A.
Then, 2A = Ae^(r*5), or 2 = e^(5r).
Taking the natural log of both sides: ln 2 = 5r. Then r = (ln 2)/5 = 0.14
The interest rate would have to be 13.86% per year, written here as r=0.14.
First, you do 18 miles times 3 hours.
The answer is 54
The you do 15 miles time 2 hours
The answer is 30
You can add them all up and get 84 miles total. (D)

hope this helps, good luck!!!
Answer:
Option B. 9 ml.
Step-by-step explanation:
Recommended dose of a drug = 5 mg/kg body weight.
weight of the cat = 8 lb
1 lb = 0.4536 kg.
8 lb = 0.4536 × 8 = 3.6288 kg. ≈ 3.6 kg
A solution contains a concentration of 2 mg/ml
so recommended dose for 3.63 kg = 5mg × 3.6 = 18 mg
∵ 1 ml. contains a concentration = 2 mg
∴ for 18 mg concentration dose will be = 18/2 = 9 ml
9 ml of the solution should be given to a cat.
Option B. 9 ml.
