Chapter A.7, Problem 6MP

Repeat Example 6 if near the end of summer, the supply-and-demand equations are

$p=\frac{x}{80}-\frac{1}{20}$    Supply equation

$p=\frac{1,264}{x}$    Demand equation

Supply and Demand At a large summer beach resort, the weekly supply-and-demand equations for folding beach chairs are

$p=\frac{x}{140}+\frac{3}{4}$    Supply equation

$p=\frac{5,670}{x}$    Demand equation

The supply equation indicates that the supplier is willing to sell x units at a price of p dollars per unit. The demand equation indicates that consumers are willing to buy x units at a price of p dollars per unit. How many units are required for supply to equal demand? At what price will supply equal demand?
