A river has a population of 700 salmon. Due to overfishing, this population is currently declining at a rate of 5% per year. Use this sequence to find the population over the next
five years. Round to the nearest whole number.

Answer ROUNDED TO THE NEAREST WHOLE NUMBER:

f(1) 700*0.95 = 665

f(2) 665*0.95 = 632

f(3) 631.75*0.95 = 600

f(4) 600.1625* 0.95 = 570

f(5) 570.154375 *0.95 = 542

Step-by-step explanation:

Each year, you need to multiply the previous amount of salmon by 0.95, because what is left is 95% of the previous year. 1 = 100%, 0.05 = 5%, 1 - 0.05 = 100% - 5% = 95%

f(1) 700*0.95 = 665

f(2) 665*0.95 = 631.75

f(3) 631.75*0.95 = 600.1625

f(4) 600.1625* 0.95 = 570.154375

f(5) 570.154375 *0.95 = 541.646656
