Maria has to spend 5 1/2 hours to finish her community service program in a community health clinic. Last week, she was able to spend 3 3/4 hours. Which equation can be used to determine the number of hours, h, that Maria still needs to spend to complete her service program?
Options:
h - 3 3/4 = 5 1/2
h + 3 3/4 = 5 1/2
h + 5 1/2 = 3 3/4
h - 5 1/2 = 3 3/4
