A school of fish has the population of 200. The population is decreasing at a rate of 5% a year how can you write in exponential decay function to find the quarterly decay rate

Step-by-step explanation:

Initial population of fish = 200

Decay rate by which population is decreasing = 5% per year

Number of quarters in a year = 4

Rate of decay in a quarter = = 1.25%

Formula for the exponential decay in the population is,

Here, P = Final population

P₀ = Initial population

r = Rate of decay per quarter

n = Number of quarters for the total decay

By substituting these values in the formula,

the answer is b.)

< 1=< 2

x=6 and x=3
