You can put this solution on YOUR website! A company that manufactures hair ribbons knows that the number of ribbons it can sell each week, x, is related to the price p per ribbon by the equation
x=1300−100p. At what price should the company sell the ribbons if it wants the weekly revenue to be $4,200?
(Remember: The equation for revenue is R=xp.)
R = xp
4,200 = p(1,300 - 100p) ------- Substituting 4,200 for R and 1,300 - 100p for x
 ------ Factoring out GCF, 100
(p - 7)(p - 6) = 0
p, or price of each ribbon in order to realize revenue of $4,200:
