Problem:

Cell Solutions, a cell phone provider, provides a simple web app to help potential customers calculate how much it will cost to purchase cellular service through their company. This application allows users to choose from among Cell Solutions different plans, options, and devices in order to find a solution that works best for them. Customers first choose between an individual or family plan, selects which model of phone they would like along with the number they will need, then chooses which of the packages they wish to buy along with any additional options that they would like on top of that.

Cell Solutions offers the following packages:

• 800 minutes per month $15.00 per month
• 1500 minutes per month $25.00 per month
• Unlimited minutes per month $40.00 per month

Customers may also select the following options:

• Voicemail $5.00 per month
• Unlimited text messaging $10.00 per month
• 5 GB data $25.00 per month

The provider sells the following phones:

• Model 100: $129.95
• Model 110: $249.95
• Model 200: $399.95

(A 6% sales tax applies to the sale of any phone.)

With the Individual plan, the customer gets one phone. With the Family plan, the customer gets as many phones of the same model as he or she desires, and all the phones share the same minutes. A customer may also purchase any amount of data that they desire in 5 GB increments.

Voicemail and text messaging fees are charged for each phone purchased under the Family plan, but data is shared among all phones, similar to minutes.

The user enters the number of phones, selects the phone model, options, and package. When the Calculate button is clicked, the charges are calculated and displayed. A customer is provided with their monthly rate as well as any one-time costs associated with their selection.
