Research can give you a great deal of information, but you will have to use your math skills to make it more useful. For example, imagine you are interested in opening a dog care service, and you have gathered the following facts:
• In 2000, the U.S. Census Bureau estimated that there were 2.67 people per household.
• According to your city’s public records, the population of your community is 80,000.
• The U.S. Pet Ownership & Demographics Source-book estimates that the number of dog-owning households in a community equals 0.361 multiplied by the total number of households.
• This Source-book also estimates that the number of dogs in a community equals 0.578 multiplied by the total number of households, or 1.6 multiplied by the number of dog- owning households.

Calculate:
a. The number of dog-owning households in your community.

b. The number of dogs in your community.
