I NEED TO FINISH UP THIS PROGRAM ITS DUE TONIGHT AT 12PM

Serious HELP Please _ My Final Project

My programs runs I am just missing a few things

I Need help with number 2 and i have to use the queues class that i posted below.

*PLEASE READ BEFORE YOU ANSWER THANKS IN ADVANCED*

Directions for the Lemonade Stand Game using Queues Create your very own lemonade stand and run a simulation for 30 days to try and make some money. 1. Start each day with a weather report. This is where you find out what kind of weather your day will have. The weather will change every day. Set up your weather reports so that some days it will rain some days will be hot and sunny, some days will be cloudy and cool. 2. Use a Queue structure to represent customers standing in line. The average number of customers will be 10 per hour. Establish your parameters so that the average number of customers per hour is dependent upon the weather. On rainy days, you will have a decrease in customers - with a random range from no customers up to 2 per hour, hot and sunny days you will have a significant increase in customers up to 10 per hour, and on cloudy and cool days you will have a mediocre amount of customers - up to 4 per hour Do you think people will want to stop and buy lemonade in the rain? Probably not, so you might not want to make any lemonade at all on those days. Some days it will be hot and sunny and on those days, you will want to make plenty of lemonade to sell. 3. Start your business with $100 in assets. You will have the following business expenses: a. Lemons i. Lemons will range in price from $1.00 each, 2 for a dollar, or 3 for a dollar. Use b. Sugar c. Ice d. Water one lemon per cu i. Sugar will cost either S.25 cents a cup or S.50 cents a cup. i. Ice will cost $.05 cents a cup or S.10 cents a cup. i. . Water will cost $.05 cents a cup Cups will cost $.02 cents a cup. Each sign will cost S.25. For each sign you purchase, your number of customers will e. Cups i. f. Advertising i. increase by 1% 4. You will have three parameters that affect vour business: cost per glass, advertising, charge per glass, a. How much it will cost you to make one glass of lemonade. Have this cost change everyday in terms of the cost of lemons, sugar, ice, and cups. Randomly generate the cost of each per day and then base how much you will buy of each on how much each costs. Decide how many glasses of lemonade to make for the day. Remember how much the COST PER GLASS i:s before you spend too much. After you have determined each of the parameters, begin your scenario You will have advertising expenses. This will be how much you pay for signs. Each sign costs 256. Determine each day whether you want to advertise and how many signs you want to purchase. Have the number of customers increase by 1% per sign Next you will decide how much to charge for each glass of lemonade. Be careful! People won't buy your lemonade if you charge too much. But remember, you must charge more then what it costs to make each glass to make any money at all. Have the weather be a factor irn how much you charge your customers b. c. Did your ASSETS go up? If so, you made money!! At the end of a day generate a statement that tells you how much you charged per glass, how many glasses you made, and how many you sold. Add up the expenses, which is the money you spent on signs and making lemonade. Your NET PROFIT is how much money you made that day. Keep track of your days in terms of which day of the month it is. Will you make more money on a weekend? Or perhaps you make more money during lunch time on a week day? These can be other factors to take into consideration You MUST use a queue structure for the customers standing in line! Remember you have 30 days of following the steps above to try and make a bunch of money! GOOD LUCK
