Answer
Find out the do they have enough tickets altogether for a prize that is worth 100 tickets .
To prove
For each balloon game you win at the fair, you get 5 tickets.
Jamal won 9 balloons games.
Thus
Total number of tickets Jamal have = 9 × 5
= 45 ticket
Gary won 6 balloon games.
Total number of tickets Jamal have = 6 × 5
= 30 ticket
Total number of ticket Jamal and Gary have = 45 + 30
= 75 tickets
No, they do not have enough tickets altogether for a prize that is worth 100 tickets .
