i'm using a ti 83

all 480 tickets for a school concert were sold. Seats in the front part of the hall cost $6 each, and seats in the back part of the hall cost $4 each. The total receipts were $2530.

This information can be represented by the system f+b=480, 6f+4b=2530

Graph the system to determine the number of tickets sold for each part of the hall.

SCIENCE is way better, at least science has a logical way of explain why thing work...

Math lacks that so badly, so it's a piece of shyt.

And NOBEL PRIZE doesn't ofter any rewards for finding new discovries in math. That's why math sucks.


Agree?
