Answer: *a general admission ticket is $160 *a grandstand ticket is $390
Explanation: make 2 equations from the provided information **g is a grandstand ticket and a is a general admission ticket.
4g+2a=1880, 4g+4a=2200 Steps: 4g+2a=1880 changes to 4g=1880-2a because you move the 2a in order to solve for g. You can substitute the 4g into 4g+4a=2200 to get 1880-2a+4a=2200 and simplify to get 1880+2a=2200. subtract 1880 from both sides and you get 2a=320. divide both sides by 2 to get a=160. After that you can substitute the value for a into 4g+4a=2200 to get 4g+4(160)=2200. simplify to get 4g+640=2200. subtract 640 from both sides to get 4g=1,560. divide both sides by 4 to get g=390.
