Question

The population of a certain town doubles every decade if the population of the town in 2016 was 52000 what was the population of the town in 1986❓❓❓❓​

Answer 1

Answer:

Let the population of town in1986 be P

Between 2016 and 1986 there are 3 decades

we will apply compound interest formula

P(2016)=P(1986)(1+100/100)^3 {100/100 since it is doubling that is 100% increase rate}

52000= P(1986)×8

P(1986) =52000/8=6500
