Q3 A package service company offers overnight package delivery to its business cus- tomers. It has recently decided to expand its facilities to better satisfy current and pro- jected demand. Current volume totals two million packages per week at a price of $12 each, and average variable costs are constant at all output levels. Fixed costs are $3 million per week, and profit contribution averages one-third of revenues on each delivery (profit contribution=(p–AV C)Q). After completion of the expansion project,...

10. The cost of sending a package by an express delivery service is $16.00 for the first two pounds, and $6.00 for each extra pound or a fraction of a pound. If the package weighs more than 80 pounds, a $25.00 excess weight surcharge is added to the cost. No package over 180 pounds will be accepted. Write a program that accepts the weight of a package in pounds and computes the cost of mailing the package with proper messaging....
