Algebra.Com's Answer #157344 by Theo(13342)![]() ![]() You can put this solution on YOUR website! Suppose you are offered two jobs. One pays $30,000 the first year with annual raises of $2000 each year. The second offers a starting salary of $27,000 and raises of 8% each year. At the end of ten years, what would your yearly salary be from a) the first job? b)the second job? \n" ); document.write( "----- \n" ); document.write( "If we assume that the salary increase is at the end of each year, we get the following: \n" ); document.write( "----- \n" ); document.write( "first job would be $30,000 + (10 * $2,000) = $50,000 \n" ); document.write( "----- \n" ); document.write( "second job would be $27,000 * (1.08)^10 = $58,290.97 \n" ); document.write( "----- \n" ); document.write( "If we assume that the salary increase is at the beginning of each year, we get the following: \n" ); document.write( "----- \n" ); document.write( "first job would be $30,000 + (9 * $2,000) = $48,000 \n" ); document.write( "----- \n" ); document.write( "second job would be $27,000 * (1.08)^9 = $53,973.12 \n" ); document.write( "----- \n" ); document.write( "It doesn't really matter whether you used 9 years or 10 years \n" ); document.write( "because you will be making more money at the second job either way. \n" ); document.write( "----- \n" ); document.write( "They are asking: \n" ); document.write( "----- \n" ); document.write( "At the end of ten years, what would your yearly salary be from a) the first job? b)the second job? \n" ); document.write( "----- \n" ); document.write( "This is nebulous and clearly open to interpretation.
