To determine the number of hours \( h \) that Maria still needs to spend to complete her community service program, we can start with the total hours required and subtract the hours she has already completed.
Maria needs a total of 512 hours. She has already spent 334 hours.
The equation to represent the relationship would be:
\[ h = 512 - 334 \]
This equation allows us to solve for \( h \), which represents the remaining hours Maria needs to complete her community service program. If you solve the equation, you can find out how many more hours she needs to work.
