Answer:
John will need 34 more tickets to be able to go on all the rides he wants
Step-by-step explanation:
To solve this, we need to first of all know the total cost in terms of tickets of all the rides that john wants to have.
This will be
cost of roller coaster ride = 19 tickets
cost of bumper car ride = 3 tickets
cost of merry-go-round ride = 33 tickets
Total cost of rides = 19 + 3 + 33 =55 tickets
Next, we will need to find the number of tickets that John has left after losing 10 of them.
This will be 31 - 10 = 21 tickets left
To find the number of more tickets that John needs , we will subtract the number of tickets he has left from total ride ticket cost.
This will be 55-21 = 34 tickets.
Hence, John will need 34 more tickets to be able to go on all the rides he wants

Step-by-step explanation:
Let T be the total number of points required to advance.

Isolate b in order to find out how many points they need in the district match:

They need to score (T - a - c - d)/3, in the district match in order to win.
