Answer:
58
Explanation:
You want to know how many tickets Fred needs for rides that cost 33, 17, and 30 tickets, given that Fred had 32 tickets, but lost 10 of them.
Ride cost
The cost of the rides Fred want to ride is ...
33 +17 +30 = 80 . . . . tickets
On hand
The number of tickets Fred has is ...
32 -10 = 22
Needed
The number he needs is the difference between the ride cost and the tickets he has:
needed = 80 -22 = 58
Fred needs 58 more tickets.
