Let x=amount of Lemon Drops needed
\n" ); document.write( "Value of Lemon Drops=1.90x ($ understood)
\n" ); document.write( "100-x=amount of Jelly Beans needed
\n" ); document.write( "Value of Jelly Beans 1.20(100-x)
\n" ); document.write( "Value of final mixture=1.48*100
\n" ); document.write( "Value of Lemon Drops plus value of Jelly Beans taken separately has to equal the value of the final mixture, so:\r
\n" ); document.write( "\n" ); document.write( "1.90x+1.20(100-x)=1.48*100 get rid of parens (distributive property)
\n" ); document.write( "1.90x+120-1.20x=148 subtract 120 from each side
\n" ); document.write( "1.90x+120-120-1.20x=148-120 collect like terms
\n" ); document.write( "0.70x=28 divide each side by 0.70
\n" ); document.write( "x=40 lb---------------------------amount of Lemon Drops needed
\n" ); document.write( "100-x=100-40=60 lb--------------amount of Jelly Beans needed\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "1.90*40+1.20*60=1.48*100
\n" ); document.write( "76+72=148
\n" ); document.write( "148=148\r
