Hey there!
You would have $2.10 left.
If you play each game twice, we can multiply the price of each game by 2, to get the price of two games.
Ring toss ~ 1.20 x 2 = 2.40 ~ $2.40 for 2 games
Balloon pop ~ 1.25 x 2 = 2.50 ~ $2.50 for 2 games
Basketball ~ 1.50 x 2 = 3.00 ~ $3 for 2 games
Then, we can add this all together:
2.40 + 2.50 + 3.00
7.90
Then, we can subtract $7.90 from the starting budget, $10.00
You get $2.10.
Hope this helps! Good luck! Have a great day!
