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.
Hope this helped! :)
8 calculate the problem and you get your answer :)
D is the only viable answer among these, as A, B, and C all contain two even integers which, by definition, have a greatest common factor of 2.
<em>Correction: </em>I was incorrect in saying that <em>all </em>even integers have a greatest common factor of 2; 2 is at least guaranteed to be <em>one of the common factors </em>in any group of even numbers, but these examples all have it as their <em>greatest </em>common factor as well.
The answer in this case would be D.
