Let x=amount of gummy bears needed
\n" ); document.write( "($understood)
\n" ); document.write( "Value of the gummy bears=2.40x
\n" ); document.write( "Then 10-x=amount of jelly beans needed
\n" ); document.write( "Value of the jelly beans=1.60(10-x)=16-1.60x\r
\n" ); document.write( "\n" ); document.write( "Now we know that the value of the gummy bears (2.40x) plus the value of the jelly beans(16-1.60x) has to equal the value of the final mixture (1.95*10). So, our equation to solve is:
\n" ); document.write( "2.40x+16-1.60x=1.95*10 subtract 16 from each side and simplify
\n" ); document.write( "2.40x+16-16-1.60x=19.5-16 collect like terms
\n" ); document.write( "0.80x=3.5 divide each side by 0.80
\n" ); document.write( "x=4.375 lbs-----amount of gummy bears needed
\n" ); document.write( "10-x=10-4.375=5.625 lbs-----amount of jelly beans needed
\n" ); document.write( "CK
\n" ); document.write( "2.40*4.375 +1.60*5.625=1.95*10
\n" ); document.write( "10.5+9=19.5
\n" ); document.write( "19.5=19.5\r
