Twenty years ago a small town in Texas had a population of 10,000. The population has increased 8% each year since then. Predict
fenix001 [56]

Answer: After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.

Step-by-step explanation:

Since we have given that

Initial population 20 years ago = 10,000

Rate of growth = 8%

Number of years = 10+20 = 30 years

According to question, we will use "Compound interest":

Amount=P(1+\frac{r}{100})^n\\\\Amount=10000(1+\frac{8}{100})^{30}\\\\Amount=10000(1+0.08)^{30}\\\\Amount=10000(1.08)^{30}\\\\Amount=100626.57

Hence, After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.
