The “pert” model

the “pert” model A=Pert can be used to model exponential growth. If we
let t=0 mean September 2020, there were approximately 3,098 new covid cases in the U.S. at t=0. In October, t=1, there were approximately 4,053 new covid cases.
a) Substitute this data into the “pert” model to find P and r.
b) Use the resulting “pert” model to predict the number of new covid cases in December 2020
