teenagers need at least 1200 mg of calcium a day.
\n" ); document.write( " one cup of milk cantains 300 mg of calcium.
\n" ); document.write( " one cup of ice cream contains 150 mg of calcium.
\n" ); document.write( " suppose a teenager drinks 2 cups of milk a day, how many cups of ice cream could he eat?
\n" ); document.write( ":
\n" ); document.write( "Let c = cups of ice cream required
\n" ); document.write( ":
\n" ); document.write( "Milk + ice cream => 1200 mg
\n" ); document.write( "300(2) + 150c => 1200
\n" ); document.write( "600 + 150c => 1200
\n" ); document.write( "Subtract 600 from both sides
\n" ); document.write( "150c => 1200 - 600
\n" ); document.write( "150c => 600
\n" ); document.write( "divide both sides by 150
\n" ); document.write( "c = \"600%2F150\"
\n" ); document.write( "c => 4 cups of ice cream
\n" ); document.write( ":
\n" ); document.write( "We can say if he consumes 2 cups of milk, he should have 4 or more cups of ice cream \n" ); document.write( "
\n" );
