The stingray population in a particular reef is decreasing at a rate of 1.4% per year. the population was 3800 in the year 2008. what is the best prediction of the population in the year 2013? round to the nearest whole number.

3541

Step-by-step explanation:

This is compound interest problem.

This takes the formula:

Where F is the future value (we want this, the population at 2013)

P is the present value (P=3800)

r is the rate of decrease (1.4% = 0.014)

t is the time frame in years (t = 5, from 08 to 13)

Putting these, we get the

Rounded to nearest whole number, the population would be around 3541
