A company manufactures cassettes. Its cost and revenue functions are C(x) = 26,000 + 30x and R(x) = 43x, respectively, where x is the number of cassettes produced and sold in a week. How many cassettes must be sold by the company to realize some profit?
x > 2,000
For making profit, revenue function is more than cost function.
R(x)>C(x)43x>26,000+30x13x>26,000x>2,000.
