Problem 16-05 To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3900, and the average first-year commission for each new account opened is $5200. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account. Determine the equation for computing Gustin’s profit per seminar, given values of the relevant parameters.

Problem 1: Mendelev Company is a small producer of several coffee products. One of the products is Kapeng Barrack’o that is sold to retail outlets. Jensen Mendelev must decide how many boxes of the Kapeng Barrack’o to produce each month. The probability that the demand will be six boxes is 0.1, for seven boxes is 0.3, for 8 boxes is 0.5, and for 9 boxes is 0.1. The cost of every box is P400, and the price that Jensen gets for each box is P800. Unfortunately, any boxes not sold at the end of the month are of no value due to spoilage. How many boxes of Kapeng Barrack’o should Jensen produce each month?
