Question

Consider that a population of fruit flies grew in a 40-day experiment. Average rate of change: 9 flies/day. Find the average growth rate from day 30 to day05​

Answer 1

Answer: Average Growth Rate is 24.19%

Explanation:

Given that;

Average rate of change = 9 flies/day

Average growth rate of change = ?

we can determine the average growth rate of change from the expression;

Average Annual Growth Rate = [((Present Value - Past Value)^1/N) - 1 ] × 100%]

Now our present value; 30th day = 9 × 30 = 270

past value; 05th day = 9 × 05 = 45

the value of N = 30 - 5 = 25

so we substitute

Average Annual Growth Rate = [((270 - 45)^1/25) - 1 ] × 100%]

= ([1.2419 - 1) × 100]

= 24.19%

Therefore Average Growth Rate is 24.19%
