# Question: In Exercise 3 101 on page 108 the price of a

In Exercise 3.101 on page 108, the price of a certain commodity (in dollars) and its total sales (in 10,000 units) were denoted by P and S. Use the joint density given in that exercise and the distribution function technique to find the probability density of V = SP, the total amount of money (in $ 10,000 units) that is spent on this commodity.
