You can put this solution on YOUR website!
let j = the number of envelopes that judy stuffs
\n" ); document.write( "let s = the number of envelopes that susan stuffs.
\n" ); document.write( "let v = the number of envelopes that valerie stuffs.
\n" ); document.write( "your equation is:
\n" ); document.write( "s + j + v = 90
\n" ); document.write( "you are given that:
\n" ); document.write( "susan stuffs twice as many as judy stuffs.
\n" ); document.write( "this means that:
\n" ); document.write( "s = 2j
\n" ); document.write( "you are also given that:
\n" ); document.write( "valerie stuffs 3 times as many envelopes as judy stuffs.
\n" ); document.write( "this means that:
\n" ); document.write( "v = 3j
\n" ); document.write( "in your equation of:
\n" ); document.write( "s + j + v = 90
\n" ); document.write( "replace s with 2j and replace v with 3j to get:
\n" ); document.write( "2j + j + 3j = 90
\n" ); document.write( "add them all together to get:
\n" ); document.write( "6j = 90
\n" ); document.write( "divide both sides of the equation by 6 to get:
\n" ); document.write( "j = 90/6 = 15
\n" ); document.write( "that's the number of enevelopes that judy stuffs.
\n" ); document.write( "susan stuffs twice as many which is equal to 30
\n" ); document.write( "valerie stuffs three times as many which is equal to 45.
\n" ); document.write( "15 + 30 + 45 = 45 + 45 = 90
\n" ); document.write( " \n" ); document.write( "
\n" );
