The population of Pallet Town increases by 15% every year. If there are currently 190,000 people living there, what will be the population in 13 years?
If necessary, round your answer to the nearest whole number.
4 people.
22,972 people.

Due to its weakening steel industry, Canalave Town has been experiencing a population decline of 10% every year. The current population is 74,000 people. Assuming the trend continues, which equation projects the population in x years?
y = 74,000 (0.10)x
y = 74,000 (0.90)x
y = 74,000 (1.10)x
y = 74,000 (1.90)x
The number of research papers in Professor Sycamore area of expertise has been increasing by 5% every year. Given that 30,010 research papers were published this year. Assuming the trend continues, which equation projects the amount of research papers published in x years?
y = 30,010 (.05)x
y = 30,010 (1.05)x
y = 30,010 (.95)x
y = 30,010 (5)x
