Answer:
last year it was 80k
Step-by-step explanation:
Population increases by 5% every year
Last year it was 80,000
PRESENT POPULATION
Present population = 80,000 + 5% off 80,000
= 80,000 + 5/100 × 80,000
= 80,000 + 5 × 800
= 80,000 + 4,000
= 84,000
AFTER ONE YEAR
After this , the population again increases by 5%
Population = 84,000 + 5% off 84,000
= 84,000 + 5/100 × 84,000
= 84,000 + 5 × 840
= 84,000 + 4,200
= 88,200
ANSWERS
The population of present year is 84,000
After one year , the population becomes 88,200
Hope it helps :-)
Answer:
1. The Present population is 84,000
2. The next years population 88,200 and the year after that would be 92,610
Step-by-step explanation:
If you take the previous year and multiply it by 1.05 you you get the current population. After that you take the current population and multiply it again by 1.05 since the population increases by 5% so continue multiplying by 1.05 to get the later years and so forth
