An antiques dealer bought c antique chairs for a total of x dollars. The dealer sold each chair for y dollars.
(a) Write an algebraic expression for the profit, P, earned from buying and selling the chairs.
(b) Write an algebraic expression for the profit
per chair.
(a) \(P=cy−x\) (b) Profit per chair: \(\frac{P}{c} = \frac{cy-x}{c} = y - \frac{c}{x}\)
The dealer sold c chairs, and each chair sold for y dollars
So, revenue =
cyExpenses =
x (the dealer paid x dollars for the chairs)

P =
cy -
x(b) Write an algebraic expression for the profit
per chair.
If the TOTAL profit = cy - x,
then the profit
per chair = \(\frac{cy - x}{c}\)
Cheers,
