To find the number of hours, \( h \), that Maria still needs to spend to complete her community service program, you can start with the total hours required and subtract the hours she has already completed.
The total time required for the program is \( 5 \frac{1}{2} \) hours, and she has already completed \( 3 \frac{3}{4} \) hours. The equation would be:
\[ h + 3 \frac{3}{4} = 5 \frac{1}{2} \]
This means that the number of hours she still needs to complete, \( h \), plus the hours she has already completed, \( 3 \frac{3}{4} \), equals the total hours required, \( 5 \frac{1}{2} \).
So the correct equation is:
h + 3 3/4 = 5 1/2
