Brad sold tickets to a track meet. It cost $6 for an adult ticket and $3 for a student ticket. Let x represent the number of adult tickets sold and let y represent the number of student tickets sold. Find the intercepts. What does each intercept represent?
\n" ); document.write( ":
\n" ); document.write( "I think you are missing something in the way this problem was written, the total
\n" ); document.write( "value of the tickets sold has to be known to make logical equation.
\n" ); document.write( ":
\n" ); document.write( "In order to help you, I will assign a total value of $450 and proceed from there
\n" ); document.write( ":
\n" ); document.write( "Adult$ + Child$ = 450
\n" ); document.write( ":
\n" ); document.write( "6x + 3y = 450
\n" ); document.write( ":
\n" ); document.write( "The best way to understand intercepts, is to graph it
\n" ); document.write( ":
\n" ); document.write( "Put the equation in the general \"y=\" form
\n" ); document.write( "6x + 3y = 450
\n" ); document.write( "3y = 450 - 6x
\n" ); document.write( "Divide equation by 3:
\n" ); document.write( "y = 150 - 2x
\n" ); document.write( ":
\n" ); document.write( "Plot the positive values:
\n" ); document.write( "for x = 0, then y = 150
\n" ); document.write( "for x = 50 then y = 50
\n" ); document.write( ":
\n" ); document.write( "If you join these coordinates with a straight line it should look this:
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-20%2C+100%2C+-20%2C+200%2C+150-2x%29+\"
\n" ); document.write( ":
\n" ); document.write( "Notice the intercepts
\n" ); document.write( "y intercept occurs when x = 0
\n" ); document.write( "That's when only children's tickets are sold. 150 of them 150*3 = $450
\n" ); document.write( ":
\n" ); document.write( "x intercept occurs when y = 0
\n" ); document.write( "That's when only adult tickets are sold. 75 of them; 75 * 6 = $450
\n" ); document.write( ":
\n" ); document.write( "The rest of the graph is when there is a combination of the two
\n" ); document.write( "ie 50 adults, 50 children: (50*6) + (50*3) = $450
\n" ); document.write( ":
\n" ); document.write( "Did this help you understand this concept?\r
