Question

the population of timbuktu in 2000 was 54453. It is known that the population P is decreasing at a rate of 37 people per year. What will the population in the year y be?
a p =37y - 54453
b p = 54453 - 37y
c p = 54452 - 2000 x 37
d p = 128453 - 37y
e none of the above

Answer 1

hint: the equation will be in the form

\[\huge X_2 = X_1 + kt\]
where:
X_2 is the final population
X_1 s the initial population
k is the constant
t is the time

does that help?
