In order to determine the number of hours that Maria still needs to spend to complete her service program, we need to subtract the number of hours she has already spent from the total number of hours required.
The total number of hours required is 5 1/2 hours, and the number of hours Maria has already spent is 3 3/4 hours.
Therefore, the equation that can be used to determine the number of hours, h, that Maria still needs to spend to complete her service program is:
h = 5 1/2 - 3 3/4
Simplifying this equation, we get:
h = 11/2 - 15/4
To find a common denominator for 2 and 4, we can multiply 2 by 2 to get 4.
h = 11/2 - 15/4
h = 22/4 - 15/4
h = 7/4
Therefore, the correct equation is:
h = 7/4
None of the answer choices provided match this equation, so the question is likely incomplete or there is a mistake in the given information.
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?
A. h - 5 1/2 = 3 3/4
B. h + 5 1/2 = 3 3/4
C. h - 3 3/4 = 5 1/2
D. h + 3 3/4 = 5 1/2
