Question 304651: We’ll think about the laws of supply and demand of widgets. Let S be supply (the number of widgets available), D be demand (the number of widgets that people want) and x the price of one widget in dollars. Let’s use the equations S = 4000 + 200x and D = 9000 – 100x to represent each. Please draw the graph of these functions. These equations represent the way a normal economy works. Please answer the following questions:
What happens to the supply as price increases? Why do you think this happens?
What happens to the demand as price increases? Why?
The price at which supply and demand are equal is called the Equilibrium Price. Calculate it for this example.

Question 305345: The compound inequality b > 4 and b > 17 has the same solutions as:

A. b > 4
B. b > 17
C. 4 < b < 17
D. b < 4 or b < 17

First we must understand these two seperate inequalities.
b > 4 means that b is the set of values greater than 4
b > 17 means that b is the set of values greater than 17
We can note that b > 17 is a subset of the values of b > 4.
Hence, the compound of b > 4 and b > 17 is
A. b > 4
