Bob received $14,000 inheritance and divided it between a mutual fund that
\n" ); document.write( "yielded a yearly return of 5% and a 1-year CD that paid 3.5% annually.
\n" ); document.write( " If his total earnings for the year on this investment was $640, how much did
\n" ); document.write( " he invest in each of these two funds?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt invested at 5%
\n" ); document.write( "The total was given as 14000, therefore
\n" ); document.write( "(14000-x) = amt invested at 3.5%
\n" ); document.write( ":
\n" ); document.write( "Write a total interest equation in decimal form
\n" ); document.write( ".05x + .035(14000-x) = 640
\n" ); document.write( ":
\n" ); document.write( ".05x + 490 - .035x = 640
\n" ); document.write( ":
\n" ); document.write( ".05x - .035x = 640 - 490
\n" ); document.write( ":
\n" ); document.write( ".015x = 150
\n" ); document.write( "x = \"150%2F.015\"
\n" ); document.write( "x = $10,000 amt invested at 5%
\n" ); document.write( ":
\n" ); document.write( "I'll let you find out the amt invested a 3.5%
\n" ); document.write( ":
\n" ); document.write( "Check solution by finding the total interest using the two values
\n" ); document.write( " \n" ); document.write( "
