To determine how many games Maggie can purchase, we need to set up an equation based on the information given.
Maggie's budget is $50, and she will buy games each costing $1.99. Additionally, she will apply a $5 discount to her total purchase amount.
Let \( x \) represent the number of games Maggie purchases. The total cost of the games before using the coupon is \( 1.99x \).
After applying the coupon, the total cost becomes:
\[ 1.99x - 5 \]
Since she has a budget of $50, we want this total cost to be less than or equal to $50:
\[ 1.99x - 5 \leq 50 \]
However, the question asks for the equation that can be used to find \( x \), so we set it equal to 50:
\[ 1.99x - 5 = 50 \]
Now, rearranging that equation aligns with option D:
\[ 50 = 1.99x - 5 \]
Thus, the correct answer is:
D. 50 = 1.99x - 5.
