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 realise some profit?

Cost function: C(x) = 26000 + 3Ox Revenue function: R(x) = 43x For profit, R(x) > C(x)
⟹ 26000 + 30x < 43x
⟹ 43x – 30x > 26000
⟹ 13x > 26000
⟹ x > 2000
Hence, more than 2000 cassettes must be produced to get profit.
We know that,
Profit = Revenue – cost
Requirement is, profit > 0
According to the question,
Revenue, R(x) = 43 x
Cost, C(x) = 26,000 + 30 x; where x is number of cassettes
⇒ Profit = 43x – (26,000 + 30x) > 0
⇒ 13x – 26,000 > 0
⇒ 13x > 26000
⇒ x > 2000
Therefore, the company should sell more than 2000 cassettes to realise profit.
