A theater charges $12 for seats in the orchestra and $8 for seats in the balcony. On a certain night, a total of 360 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?	Select the correct option: A) 90 B) 110 C) 120 D) 140 E) 220
Orchestra Seats - a   Balcony Seats - b   a+b = 360   and 12a + 8b = 3320   Solving equations simultaneously (Multiply Equation 1 with 8 and subtract from second equation)   4a = 3320 - 8*360 = 3320 - 2880=

<output>440</output>
440   i.e. a= 110   and b = 360-110=

<output>250</output>
250   More seats in balcony than orchestra= b-a = 250 - 110=

<output>140</output>
140   Answer: option 140
