Maria has to spend 512 hours to finish her community service program in a community health clinic. Last week, she was able to spend 334 hours. Which equation can be used to determine the number of hours, h , that Maria still needs to spend to complete her service program?

To determine the number of hours, \( h \), that Maria still needs to spend to complete her community service program, you can set up the equation based on the total hours required and the hours she has already completed.

Maria needs a total of 512 hours, and she has already completed 334 hours. Therefore, the equation that represents the number of hours she still needs to complete is:

\[ h = 512 - 334 \]

This can also be expressed as:

\[ h + 334 = 512 \]

Either equation can be used to find the value of \( h \).
