We need to set up an equation that accounts for Maggie’s total spending, including the price of the games and the discount.

• Maggie starts with a $50 gift card.
• Each game costs $1.99.
• She also has a $5 coupon that applies to the entire purchase.

Let's define x as the number of games Maggie can purchase.

The total cost of the games would be 1.99x (since each game costs $1.99). After applying the $5 coupon, the total amount Maggie pays is 1.99x - 5.

Since she can spend up to $50, we set the total cost equal to $50:

$1.99x - 5 = 50$

This matches option D:

$\boxed{D: 50 = 1.99x - 5}$

So, option D is the correct equation.

Would you like more details on solving this equation, or do you have any other questions? Here are some related questions:

1. How do you solve the equation $50 = 1.99x - 5$ for $x$?
2. How would the equation change if Maggie didn’t have the $5 coupon?
3. What if Maggie had $60 on the gift card instead of $50? How would the equation change?
4. What is the total cost of 10 games after applying the $5 coupon?
5. What is the maximum number of games Maggie can buy if the coupon was worth $10 instead?

Tip: Always break down word problems into known values (like the price per game, gift card amount, and coupon) before translating them into an equation.
