Plot the following points of a demand and supply graph.

\n

\n

By filling in a table like the one below, drag the points A to D to the correct location.

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
 Point A(supply) B(supply) C(demand) D(demand) \$x\$ 0 100 0 100 \$y\$
\n

To be marked correctly, you only need to move the points to within 1 unit of the exact location.

Find the equilibrium price and the equilibrium quantity.

\n

Equilibrium price = [[0]]

\n

Equilibrium quantity = [[1]]

A recent industry development has affected the supply.  Supply is now modelled by the equation:

\n

\$S=\\var{t}\\ +\\ \\var{s}P\$

\n

Determine the new equilibrium quantity and price.

\n

New equilibrium quantity = [[0]]

\n

New equilibrium price = [[1]]
