Answer: 
The one with the better deal would be 30 ride tickets for $22.50 this is because you pay less money for more rides. 
Step-by-step explanation:
First you divide 20 by 14. Doing this will give you the cost of a ride per ticket. 
20/14 = 1.42 
Then you do the same thing to 30 and 22.50.
30/22.50 = 1.30
Last you compare which deal has less money per ride. 
1.42 > 1.30
