Question 1056346: A store selling typewriter ribbons knows that the number of ribbons it can sell each week, x, is related to the price per ribbon, p, by the equation x=1900-140p. Write an expression for the weekly revenue that involves only the variables R and p. (Remember: The equation for revenue is R=xp.)
Please help me. Im so confused :(

You can put this solution on YOUR website! A store selling typewriter ribbons knows that the number of ribbons it can sell each week, x, is related to the price per ribbon, p, by the equation x=1900-140p. Write an expression for the weekly revenue that involves only the variables R and p. (Remember: The equation for revenue is R=xp.)
---------------------
R(p) = x*p = (1900-140p)p = 1900p - 140p^2
