Kadeesha needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.25 hours and charged her $91 for parts. The total was $367.25. Which tape diagram could be used to represent the context if cc represents the cost of labor per hour?

To find the correct tape diagram that represents the context of Kadeesha's computer repair costs, we can break down the total costs involved.

We have:

1. The technician worked for 4.25 hours, charging an hourly rate \( c \) for labor.
2. The cost of parts is given as $91.
3. The total cost is $367.25.

We can express the total cost as:
\[
\text{Total Cost} = \text{Cost of Parts} + \text{Cost of Labor}
\]
\[
367.25 = 91 + 4.25c
\]

From this equation, we can observe that the cost for labor (represented by \( 4.25c \)) and the fixed cost for parts ($91) contribute to the total cost ($367.25).

Now let's analyze the provided tape diagram options:

- **Option A:**
- Shows \( c \) for labor repeated 4.25 times, followed by the cost of parts (91), and it sums up to \( 302.25 \). This doesn't correctly represent the total cost.

- **Option B:**
- Shows the cost of parts repeated (91) and the labor \( c \) but does not correspond with the total cost or labor length.

- **Option C:**
- Shows \( c \) for labor repeated (4.25 times), includes the cost of parts (91) with a total represented as \( 367.25 \). This aligns with our understanding of the total cost.

- **Option D:**
- Like option B, it repeats the cost for parts but misrepresents the labor cost.

Thus, the best tape diagram that represents the context is:

**C**
