Christian sold tickets to the game. Good seats were $5 each and poor seats cost $2 each. 210 people attended and paid $660. How many of each type of seat were sold

People who purchased good seats will be labeled as a

people who purchased poor seats will be labeled as b

therefore ...

5a + 2b = 660

a + b = 210

Now, all that has to be done is for the system to be solved.

-2 (a+b=210)

5a + 2b = 660

-2a - 2a = - 420

3a=240

a = 80

*3 people purchased good seats.

Now we can plug that number in

5 (80) + 2b = 660

400 + 2b = 660

2b = 260

b = 130

*130 people purchased poor seats
