Tickets for section A cost $a and tickets for section B cost cost $b.
\n" ); document.write( "johana piad $105 for 5 section A tickets and 3 section B tickets. raiyah paid $63 for 4 section A tickets and 1 section B ticket
\n" ); document.write( "i)write two equations in a and b to represent the information above.
\n" ); document.write( "Value Eq:::: 5a + 3b = 105 dollars
\n" ); document.write( "Value Eq:::: 4a + b = 63 dollars
\n" ); document.write( "--------------------
\n" ); document.write( "ii) calculate the values of a and b.
\n" ); document.write( "Modify the equations:
\n" ); document.write( "Multiply thru the 1st equation by 4.
\n" ); document.write( "Multiply thru the 2nd equation by 5.
\n" ); document.write( "20a + 12b = 4*105
\n" ); document.write( "20a + 5b = 5*63
\n" ); document.write( "------------------------
\n" ); document.write( "Subtract the lower from the upper equation:
\n" ); document.write( "7b = 105
\n" ); document.write( "b = 17 (price of section B tickets)
\n" ); document.write( "----
\n" ); document.write( "Substitute and solve for \"a\":
\n" ); document.write( "4a + 17 = 63
\n" ); document.write( "4a = 46
\n" ); document.write( "a = 11.50 (price of section A tickets)
\n" ); document.write( "===========================================
