Q:
Assume that the demand curve D(p) given below is the market demand for widgets:
Q = D(p) = 1604 - 16p, p > 0
Let the market supply of widgets be given by:
Q = S(p) =
4 + 8p, p > 0
where p is the price and Q is the quantity. The functions D(p) and S(p) give the number of widgets demanded and
supplied at a given price.

Price & Demand
In economic theory, we let z represent the number of items (called demand) a supplier will produce if the
price of the item is p.
For a particular item, if the price is $10 per item, then the demand is 577 items. However, if the price is
raised to $33 per item, then the demand decreases to 393 items.
Using this information, find the demand equation as a function of the price p?

Suppose that Raphael and Susan are the only suppliers of pieces of cake in some hypothetical market. Their annual supply schedules are given
by the following table:

PRICE (Dollars per piece)
On the following graph, plot Raphael's supply of pieces of cake using the green points (triangle symbol). Next, plot Susan's supply of pieces of cake
using the purple points (diamond symbol). Finally, plot the market supply of pieces of cake using the orange points (square symbol).
Note: Line segments will automatically connect the points. Remember to plot from left to right.
