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?(1 point)
Responses

h − 334 = 512
h minus 3 and three-fourths equals 5 and one-half

h + 512 = 334
h plus 5 and one-half equals 3 and three-fourths

h − 512 = 334
h minus 5 and one-half equals 3 and three-fourths

h + 334 = 512

1 answer

To determine how many hours Maria still needs to spend to complete her community service program, we start with the total hours required and subtract the hours she has already completed.

  1. Total hours required: \(5 \frac{1}{2}\) hours = \(5.5\) hours
  2. Hours already spent: \(3 \frac{3}{4}\) hours = \(3.75\) hours

The equation to find the remaining hours \(h\) can be set up as follows:

\[ h + 3.75 = 5.5 \]

Now, rearranging this equation gives us:

\[ h = 5.5 - 3.75 \]

Since we want the equation that reflects the remaining hours, it can also be represented as:

\[ h - 3 \frac{3}{4} = 5 \frac{1}{2} \]

So the correct response is:

h minus 3 and three-fourths equals 5 and one-half.
