Chapter 4.1, Problem 2E

Reminder Round all answers to two decimal places unless otherwise indicated.

World Copper Production World production of copper, in millions of tons per year, from $1900$ to $2000$ is given by

$C=0.5\times {1.033}^t$,

where $t$ is the time in years since $1900$.

a. What production level does this model give for the year $2000$?

b. If this model were extended to $2025$, how could you use your knowledge of copper production in $2024$ to estimate copper production in $2025$?
