Question 275900
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the amount invested at 4%.  Since the amounts are equal, *[tex \Large x] also represents the amount invested at 5%.  The amount of interest paid in 1 year at 4% is *[tex \Large .04x].  And the amount of interest paid on the 5% money in 1 year is *[tex \Large .05x].  The sum of these two amounts is $324, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ .04x\ +\ .05x\ =\ 324]


Just solve for *[tex \Large x].
