Kara spent 16.00 on tubes of pain and brushes for art class.
\n" ); document.write( ":
\n" ); document.write( "I didn't know you had to pay for pain, thought it just came on it's own!
\n" ); document.write( ":
\n" ); document.write( "Anyway
\n" ); document.write( "Each tube of paint cost $3.00 and each brush costs .50.
\n" ); document.write( "3p + .50b = 16
\n" ); document.write( ":
\n" ); document.write( "Kara purchases twice as many brushes as tubes of paint.
\n" ); document.write( "b = 2p
\n" ); document.write( ":
\n" ); document.write( "Find the number of brushes and the number of tubes of pain that she purchased.
\n" ); document.write( ":
\n" ); document.write( "Replace b with 2p in the 1st equation
\n" ); document.write( "3p + .50(2p) = 16
\n" ); document.write( "3p + 1P = 16
\n" ); document.write( "4p = 16
\n" ); document.write( "p = 16/4
\n" ); document.write( "p = 4 tubes of pain
\n" ); document.write( "then
\n" ); document.write( "b = 2(4)
\n" ); document.write( "b = 8 brushes
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this: 3(4) + .5(8) = 16 \n" ); document.write( "
\n" );
