Answer to Question #113636 in Algebra for Malia Losalu

Question

A bakery finds that the price they can sell cakes is given by the function p = 580 − 10x where x is the number of cakes sold per day, and p is price. The total cost function of the company is given by c = (30+5x) 2 where x is previously defined, and c is total cost.
Find the revenue and marginal revenue functions [Hint: revenue is price multiplied by quantity i.e. revenue = price × quantity] (3 marks)

Answer 1

revenue = price × quantity

R = p×q

In our case quantity is the number of cakes sold per day or x.

R = p×x

R = (580 - 10x)x= 580x - 10x²

marginal revenue MR

MR = dR/dx = 580 - 20x

Answer: R = 580x - 10x²; MR = 580 - 20x
