The population of Winnemucca, Nevada can be modeled by  $P=6191\left(1.04\right)^t$  where  $t$  is the number of years since 1990. What was the population in 1990? By what percent did the population increase each year?

• 6191 people, 4% increase

• 6191 people, 96% increase

• 6191 people, 4% decrease

• 6191 people, 96% decrease

A population of 1500 deer decreases by 1.5% per year. At the end of 10 years, there will be approximately 1290 deer in the population. Which function can be used to determine the number of deer, y, in this population at the end of t years?

• y = 1500(1 - 0.015)^t
• y = 1500(0.015)^t
• y = 1500(1 + 0.015)^t
• y = 1500(1.5)^t
