Problema Solution
The price per unit, p, and the demand, x, for a particular material are related by the linear equation
p equals 80 minus four fifths xp=80−45x,
while the supply is given by the linear equation
p equals four fifths xp=45x,
as shown in the given figure.
At what value of p does supply equal demand?

The problem statement is ambiguous. This would appear to request a solution for the equations "p=(4/5)x" and "p=80-(4/5)x". The statement also references a 'given figure' but all inquiries must be entirely text.
The expected question is:
p=(4/5)x
p=80-(4/5)x

p=40
x=50
So when p=40 supply equals demand.
