[6.05]A concert hall earned $40,000 in sold−out comedy ticket sales. Front section tickets cost $150 per seat and back section tickets cost $50 per seat. The number of front section seats is three times the number of back section seats. How many seats are in the front section?
Let the front seats be x and the back seats be y: 150x+50y=40000 3y = x Can you solve it from here?
no i need a little more help
Sorry...phone. Give me a few
ok thanks lol
my laptops about to die lol...hurry!!!!
lol
Ok. We'll use the substitution method since that's the easiest in this case. Since x=3y plug 3y back into the first equation and solve for y. Once you know what y is, you can easily figure out x. \[150(3y)+50y=40000\]\[y=80\]Using the second equation and plugging in 80 you get:\[3(80)=x=240\]If you plug all that back into the original question you'll see that it works out :)
so x equals 240?
Yes...there are 240 front seats and 80 back seats
thanks bro
