A theater charges $12 for seats in the orchestra and $8 for seats in the balcony. On a certain night, a total of 350 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 option.
A) 90	B) 110	C) 120	D) 130	E) 220
Orchestra Seats - a   Balcony Seats - b   a+b = 350   and 12a + 8b = 3320   Solving equations simultaneously (Multiply Equation 1 with 8 and subtract from second equation)   4a = 3320 - 8*350 = 3320 - 2800= 
<gadget id="calculator">3320 - 2800</gadget>
<output>520</output>
520   i.e. a= 130   and b = 350-130= 
<gadget id="calculator">350-130</gadget>
<output>220</output>
220   More seats in balcony than orchestra= b-a = 220 - 130=
