Business and Economics: For a business to make a profit it is clear that revenue R must be greater than cost C; in short, a profit will result only if R>C. if a company manufactures records and its cost equation for a week is C = 300 + 1.5x and its revenue equation is R = 2x, where x is the number of records sold in a week, how many records must be sold for the company to realize a profit?

2x>300+1.5x
0.5x>300
X>600
Therefore,more than 600records must be sold in a week to realize profit
