Let x=amount that Sarah invested in the savings account\r
\n" ); document.write( "\n" ); document.write( "Then 3x=amount that she invested in the mutual fund\r
\n" ); document.write( "\n" ); document.write( "Interest(I)=Principal(P) times Rate(R) times Time(T) or I=PRT\r
\n" ); document.write( "\n" ); document.write( "(1) Interest on savings account=x*(0.05)*(1)=0.05x\r
\n" ); document.write( "\n" ); document.write( "(2) Interest on mutual fund=3x*(0.11)*(1)=0.33x\r
\n" ); document.write( "\n" ); document.write( "Now we are told that (1)+(2)=$152. So our equation to solve is:\r
\n" ); document.write( "\n" ); document.write( "0.05x+0.33x=152 combine like terms
\n" ); document.write( "0.38x=152 divide both sides by 0.38\r
\n" ); document.write( "\n" ); document.write( "x=$400-------------amount that Sarah invested in the savings account\r
\n" ); document.write( "\n" ); document.write( "3x=3*$400=$1200----------amount that she invested in the mutual fund\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "0.05*400+0.11*1200=$152
\n" ); document.write( "20+132=152
\n" ); document.write( "152=152\r
\n" ); document.write( "
