Answer:
64 tickets
Explanation:
First, let's find how many total tickets Cole and Bryton have so far.
Cole has 152 tickets, while Bryton has 84, so adding these yields:
152 + 84 = 236 tickets
In total, they need 300 tickets, so to find how many more they need, we must subtract 236 from 300:
300 - 236 = 64 tickets
