Work Step by Step
Situations best modeled by linear models:
1. Total cost of producing $n$ items, with (cost per item) and (fixed costs) as parameters.
2. Proportionality problems, such as:
Total number of representatives of a community at a meeting, when ($n$ people) are needed in a community to have 1 representative.
Situations best modeled by exponential models:
1. Growth of population of bacteria $t$ hours after initial time.
2. Continuous interest compounding at a given yearly rate.
