Answer:
121670
Step-by-step explanation:
The number of packages can be defined with the function:
P(t) = P(t-1)*1.15 where t = the years and 1.15 represents the 15% increase.
Packages during 2018: P(2018) = 80000
Packages during 2019: P(2019) = P(2018)*1.15 = 92000
Packages during 2020: P(2020) = P(2019)*1.15 = 105800
Packages during 2021: P(2021) = P(2020)*1.15 = 121670
