Answer: $8.25
Explanation:
Since David played 2 games and one game costs $4.50, you're gonna multiply $4.50 by 2 and that gives you $9. Then, you're gonna add the cost of the shoe ($2.75) which gives you $11.25. Since he gave the cashier a twenty-dollar bill, we're gonna subtract 11.25 by 20.00.
Therefore, the change that David will get back is $8.25
