On the water bill, typically the following is listed:

meter type, indicating whether this is a single-family residential user, multifamily resident, commercial customer, contract customer, government customer, or some other type of user.

previous months meter reading (for the last month) in thousands of gallons,

current meter reading (for current month) in thousands of gallons,

how much water has been used -- in thousands of gallons,

amount of water used during the month -- in thousands of gallons,

customer/entity name for the property being billed,

property address/location,

residential base water charge,

residential consumption water charge,

residential base sewer charge,

residential consumption sewer charge,

drainage charge,

solid waste cart fee, and, the

final amount of money billed/owed for the month.

1. Billing Rates are not listed on the bill. Assuming that the residential and other customers are billed at different rates, what computation/s are necessary to determine if a customer would be billed at the residential or some other rate? Consider the various customer types.
2. What computations must be used to process the data that determines the final amount of money owed for the month, after the first months rate increase. In other words, how will that increased amount be computed? The water rate, using the information in the article, will increase by 9% for water charges and 20% for wastewater/sewer charges, drainage charges, and solid waste cart fees.
