(Effective raise is the raise that is actually realized after adjusting for inflation.) 5. Is it reasonable to pay a million dollars today for a house that was sold for $320,000 in 2000? answers . Why or why not? Do the necessary calculations and provide relevant reasons to justify your 6. You have been making $45,000 a year in salary and have not had a raise since 2012. You are now up for a performance evaluation. Knowing that a positive review usually leads to a salary increase, you would like your boss to know how much of a minimum raise he/she should give you in order for you to afford everything you could afford in 2012. Draft a short, but formal, email to your boss to request a salary increase based on your calculations. 7. Table 1 provides the historic tuition rates for full-time, in-state students in the California State University system between 2007 and 2018. The third column of Table 1 provides the 2007- 2008 tuition rate in the current dollars. That is, for example, if there had not been any increase in tuition, it would have cost 2,921 dollars to attend a CSU during the 2008-09 fiscal year after adjusting for inflation. That is, $2,921 is the "fair value" of the same quality education that one would receive in 2007-2008 (d) Fiscal year Undergraduate tuition ($) 2007-08 tuition in current $ (Fair value) 2007-08 2,772 2,772 2008-09 3,048 2,921 0012 2009-10 4,026 (190) 2,878 2010-11 4,440 2,911 2011-12 5 , 472 3,020 2012-13 5 , 472 3,017 9090Ssbim 2013-14 5 , 472 ells aboo In so land's to O'S 3,118 2014-15 5, 472 3,171 2015-16 5,472 3,177 2016-17 5,472 3,211 2017-18 5, 742 3,273 Table 1: California State University full-time, in-state student tuition rates per academic year (6.1 units or greater). a. Based on the information in Table 1, what was the inflation rate from 2007-08 to 2008-09: What was the inflation rate from 2008-09 to 2009-10? What happened in 2009-10? b. What year did students experience the most "unfair" tuition cost when compared to 2007- 0003 08? Support your reasoning with the appropriate calculations and justify quantitatively.
