A baby elephant weighs 200 pounds at birth. Seven years later, the elephant's weight is 3,000 pounds.

What is the rate of change of the weight of the elephant?

Answer 1

3000=200 (1+r)^7
Solve for r (rate of change each year)
R=((3,000÷200)^(1÷7)−1)×100
R=47.24% increased per year

Answer 2

400/year
1.2/day
