List the basic steps to the $\textit{scientific method}$ and describe each. Explain what a $\textit{hypothesis}$ and a $\textit{thesis}$ are. What is the difference between $\textit{inductive}$ and $\textit{deductive}$ reasoning? Include why the final step in the scientific method is critical.

Manufacturing Calculators A manufacturer of calculators produces two models: standard and scientific. Long-term demand for the two models mandates that the company manufacture at least 100 standard and 80 scientific calculators each day. However, because of limitations on production capacity, no more than $200$ standard and $170$ scientific calculators can be made daily. To satisfy a shipping contract, a total of at least $200$ calculators must be shipped every day.

(a) If the production cost is $\$ 5$ for a standard calculator and $\$ 7$ for a scientific one, how many of each model should be produced daily to minimize this cost?

(b) If each standard calculator results in a $\$ 2$ loss but each scientific one produces a $\$ 5$ profit, how many of each model should be made daily to maximize profit?
