A theater charges $12 for seats in the orchestra and $8 for seats in the balcony. On a certain night, a total of 355 tickets were sold for a total cost of $3,320. How many more tickets were sold that night for seats in the balcony than for seats in the orchestra?  Choose the correct choice from the following answers.
A) 90 B) 115 C) 120 D) 130 E) 220
Orchestra Seats - a   Balcony Seats - b   a+b = 355   and 12a + 8b = 3320   Solving equations simultaneously (Multiply Equation 1 with 8 and subtract from second equation)   4a = 3320 - 8*355 = 3320 - 2840=

480   i.e. a= 120   and b = 355-120=

<output>235</output>
235   More seats in balcony than orchestra= b-a = 235 - 120=
