A set X is said to be closed under multiplication if for every x1,x2 ∈ X we have x1x2 ∈ X. Let A be the union of all bounded subsets X ⊆ R that are closed under multiplication. Does inf(A) exist? If it does, find it.

S&J Plumbing, Inc.'s 2010 income statement shows a net profit before tax of $468, whereas the balance sheet that the company's equity for the fiscal year-end 2010 is $1,746.

Calculate: What is the population change/growth, natural increase, and net migration for each of the four populations. Fill in the table below. Hint: estimate using the “Demographic Balancing Equation.” Hint: In the table, you can express answers absolute numbers.

Calculate: Using data from the above table/calculations, what is the net-migration rate for Oakwood during this ten-year period (2000-2010)? Hint: assume that all migration and natural increase was evenly spaced during the ten-year interval between 2000 and 2010. This assumption should help you figure out an estimate of the mid-year population for Oakwood.
