2.1 Demand 1) Suppose the demand for Digital Video Recorders (DVRs) is given by Q=250 - .25p + 4pc, where Q is the quantity of DVRs demanded (in 1000s), p is the price of a DVR, and pc is the price of cable television. How much does demand for DVRs change if the p rises by $40? A) drops by 10,000 DVRs B) increases by 16,000 DVRs C) drops by 2,500 DVRs D) increases by 4,000 DVRs Answer: A 2) Suppose the demand for Digital Video Recorders (DVRs) is given by Q=250 - .25p + 4pc, where Q is...

INTRODUCTION Dear Student Welcome to MAT1514 Pre-Calculus (Engineering). In MAT1514 you have to work independently and motivate yourself to do so regularly to be successful. See an example of a study plan further on in this letter. The amount of time you study is not important, but how efficient you use that time is very important. Because this is a fully online module, you will need to use myUnisa to study and complete the learning activities for this module. Visit the website for MAT151...
