➤ What is the basic shape and meaning of the supply curve?
The supply curve graphically shows how quantity supplied responds to price. For most goods it slopes upward: higher prices induce producers to supply more, holding other factors constant. It reflects producers’ willingness and ability, production costs, and technology. It distinguishes change in quantity supplied from shifts caused by external factors.

➤ How do you calculate opportunity cost in everyday choices?
Identify the next-best alternative you forgo and estimate its net benefit. Include explicit costs like money and implicit costs like time, lost wages, or leisure value. Then compare that benefit to the option you choose. For example, studying an extra hour has the opportunity cost of income you could have earned working.

➤ How do externalities relate to public goods and market failure?
Externalities occur when a transaction affects third parties who are not part of the market exchange. Positive externalities, like herd immunity, often accompany public goods and create benefits that producers cannot capture. This gap causes private underinvestment. The market fails to reflect full social benefits, so socially desirable public goods remain undersupplied without intervention.

➤ When should you report absolute decrease versus percent decrease?
Report absolute decrease when you need the raw change: here it is 1,050 units. Use percent decrease when you want relative impact or comparison across scales: here it is 70%. Choose absolute for quantity-sensitive contexts and percent for comparisons, trends, or communicating proportional change.
