Answer:
10 games plus entry will cost $20
for $35 you can play 20 games
Explanation:
entry is $5 and 10 games will cost $15 so as that and that's $20
$35 minus the entry is $30 divided by 1.50 (game cost) is 20. so you can play twenty games unless you've already paid the entry in which case you can play 23 games for $35
