Since one of the actors in a popular television series has been spotted wearing pink sun glasses, pink sun glasses is a must for every fashion conscious person. At the same time, a technological innovation reduces the costs of producing pink sun glasses. As a result, the equilibrium price of pink sun glasses will:
1.decrease and equilibrium quantity will either increase, decrease, or stay the same.
2.either increase, decrease, or stay the same, and equilibrium quantity could also either increase, decrease, or stay the same.
3.increase and equilibrium quantity will either increase, decrease, or stay the same.
4.either increase, decrease, or stay the same, and equilibrium quantity will increase.
What does doing mathematics mean?
Suppose we observe that the equilibrium quantity of a particular good has increased significantly over the past 5 years, with virtually no change in the equilibrium price. The most likely explanation is that, over the past 5 years:
1.supply has decreased but demand has increased.
2.both supply and demand have increased.
3.both supply and demand have decreased.
4.supply has increased but demand has decreased.

Explain the five components of a DBMS and why Dineo would need each of the (10) components for her website.
Dineo has given what she wants to display on the website a lot of thought. And she has come up with quite a comprehensive set of business rules.
Launch Data To Be Displayed
Draw an Entity Relationship Diagram (ERD) using Unified Modelling Language (UML) notation, representing these business rules. Your design should be at the logical level – include surrogate primary key and foreign key fields and remember to remove any many-to-many relationships.
