Find the population in the year 2016 and 202

Answer 1

Answer:

Step-by-step explanation:

Population of 2016 = x

Population of 2017 = 6%x + x =6/100 x + x = 106x/100

Population of 2018 = (106x/100 ) 6% + 106x/100

= (106x/100 ) 6/100 + 106x/100

=636x/10000 + 106x/100

238765=636x/10000 + 106x/100

238765=636x/10000 + 10600x/10000

238765=11236 x/10000

x= 238765*10000/11236

x= 212500

Population of 2016 = 212500

Population of 2017 = 212500*6% + 212500 = 225250

Population of 2018 =225250*6% + 225250 =238765

Population of 2019 =238765*6% + 238765 =253091

Population of 2020 = 253091 *6% + 253091 = 268277
