Question 1104635: he crime rate of a certain city is increasing by exactly
2% each year. If there were
350 crimes in the year 1990 and the crime rate remains constant each year, determine the approximate number of crimes in the year
2021

f = p * (1 + r) ^ n
f is the future value
p is the present value
r is the interest rate per time period.
n is the number of time periods.
350 crimes in 1990, so p = 350.
rate = 2% / 100 = .02 per year.
n = 2021 - 1990 = 31 years.
f = 350 * (1.02)^31 = 646.6560855 in the year 2021.
that's approximately 647.
