The population of Boringtown decreased annually by 1.8% between the year 2015-2018. In 2015, there were approximately 200,000 people living in Boringtown. Which function models the city's population since 2015?
y = 200,000(1 + 0.018)3
y = 200,000(1 - 0.18)3
y = 200,000(1 + 0.18)3
y = 200,000(1 - 0.018)3
Your shiny new boat cost $7650. The depreciation for your boat is 14% per year. You want to know the value of your boat in 3 years. What is the equation that models this problem?
