The point at which a company's profits equal zero is called the company's break-even point. let r represent a company's revenue, let c represent the company's costs, and let x represent the number of units produced and sold each day.
r(x)=12x
c(x)=6.5x+22000
a) find the firm's break-even point; that is, find x so that r=c
b) find the values of x such that r(x)> c(x). this represents the number of units that the company must sell to earn a profit.

Jenny invests $2,000 at an interest rate of 5%. the amount of money, me, in jenny's account after tyears can be represented using the equation ma-2000(1.05). if jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money mo. in her account would be represented using the equation! mg = 2000(105)*** which of the following is equivalent to mp? 2000(105) om- 1.05 2000(1.05) mo 1059 mp-2000(1.05) (105) mp - 2000(1.05) + (1.05)
