Final answer:
The equation to determine the number of hours Maria still needs to complete her service program is A. h - 3 3/4 = 5 1/2, as this represents the total time required minus the time already spent.
Step-by-step explanation:
To determine the number of hours, h, that Maria still needs to spend to complete her service program, we are looking for an equation that represents the total time required minus the time already completed.
Since the total time required for Maria's community service is 5 1/2 hours and she has already spent 3 3/4 hours last week, we want to subtract the time spent from the total time required.
The equation we need is h - 3 3/4 = 5 1/2. This equation means that whatever hours h Maria still needs to serve added to the 3 3/4 hours she has already served will equal the total requirement of 5 1/2 hours. Therefore, the correct answer is A. h - 3 3/4 = 5 1/2.
