it costs $20 for 4 play tickets and $35 for 7 play tickets. is costs per ticket constant? why or why not?
attashe74 [19]

Answer:

Yes.

Step-by-step explanation:

Most people are going to say 4x2=8 so 20x2=40, then do a huge math mess up and think they discounting $1.33 after the first 4. this is incorrect.

Seeing as $20 is 4 tickets we can safely say, each ticket is $5 each.

Basic mathematics, 5x7=35. Paying for 7 tickets at $5 each, that is the correct constant price.
