Foreclosure Crisis Starting in 2010, on the heels of the 2007– 2009 subprime mortgage crisis, the United States saw an epidemic of mortgage foreclosures, often initiated improperly by large financial institutions. Exercises 65–70 are based on the following table, which shows the numbers of foreclosures in three states during three months of 2011:13
June | July | Aug. | |
California | 54,100 | 56,200 | 59,400 |
Florida | 23,800 | 22,400 | 23,600 |
Texas | 9,300 | 10,600 | 10,100 |
Your law firm handled 10% of all foreclosures in each state in June, 30% of all foreclosures in July, and 20% of all foreclosures in August 2011. Use matrix multiplication to compute the total number of foreclosures handled by your firm in each of the states shown.

- . e-Filing Tax Returns The Internal Revenue ServiceRestructuring and Reform Act (RRA) was signed intolaw by President Bill Clinton in 1998. A major objective ofthe RRA was to promote electronic filing of tax returns.The data in the table that follows show the percentage ofindividual income tax returns filed electronically for filingyears 2004–2012. Since the percentage P of returns filedelectronically depends on the filing year y, and each inputcorresponds to exactly one output, the percentage ofreturns filed electronically is a function of the filing year; soP1y2 represents the percentage of returns filed electronicallyfor filing year y.(a) Find the average rate of change of the percentage ofe-filed returns from 2004 to 2006.(b) Find the average rate of change of the percentage ofe-filed returns from 2007 to 2009.(c) Find the average rate of change of the percentage ofe-filed returns from 2010 to 2012.(d) What is happening to the average rate of change as timepasses?arrow_forwardPhillip Cane, the managing editor of Your Life Magazine, needs to develop a forecasting system for monthly newsstand sales in order to schedule press runs.
