How do you write a linear equation to a story problem such as- the group needs to raise 1600 dollars, they sell tea for .50 cents and lemonade for .80 cents. Write a linear equation and graph it
\n" ); document.write( ":
\n" ); document.write( "Let x = no. of teas sold
\n" ); document.write( "Let y = no. of lemonades
\n" ); document.write( ":
\n" ); document.write( ".50x + .80y = 1600
\n" ); document.write( ".80y = -.50x + 1600
\n" ); document.write( "Divide both sides by .8
\n" ); document.write( "y = -.625x + 2000
\n" ); document.write( ":
\n" ); document.write( " x| y
\n" ); document.write( "------
