In recent years, the number of people in a certain country who are 100 years old or older can be estimated by the function p(t) = 1.32t − 2589.1
where
t = the year
p(t) = the number of people, in thousands, who are 100 or older.
(See Example 4.)
(a) Find p(2013)
p(2013) = thousand

Find p(2023)
p(2023) = thousand

(b) Use the function to estimate when the number of people 100 years or older will reach 100,000. (Round your answer to the nearest year.)
