Let's break this problem into its components:

The problem seems to involve solving an equation where two terms represent sales or subscriptions, and they are being summed to reach a total number.

- The first term involves the number 55, which could represent a fixed contribution (perhaps from existing subscriptions) multiplied by 250.
- The second term involves the variable \( x \), representing "additional subscriptions", multiplied by 10.
- Finally, the total number is given as 1,590 (or 1,250 in some choices).

### Analyzing the Equations:

- Option A: \( 55x + 10(250) = 1,590 \)
- Option B: \( 55(250) + 10x = 1,590 \) - **This appears to be correct based on the structure of the problem.**
- Option C: \( 55(250) + 10x = 1,250 \)
- Option D: \( 55x + 10(250) = 1,250 \)

### Correct Equation:
Looking at the options, **Option B** seems correct because it has \( 55(250) \) representing the fixed subscription sales, plus \( 10x \), which accounts for the additional subscriptions. This equals the total number of sales (1,590).

Thus, the equation to use is:

\[
55(250) + 10x = 1,590
\]

### Solving for \( x \):

Now, solving for \( x \) (additional subscriptions):

\[
55(250) + 10x = 1,590
\]

\[
13,750 + 10x = 1,590
\]

Subtracting 13,750 from both sides:

\[
10x = 1,590 - 13,750
\]

\[
10x = -12,160
\]

Dividing by 10:

\[
x = -1,216
\]

Since \( x \) represents subscriptions, a negative number indicates that Allison would need to reduce the subscriptions, which might indicate a surplus situation in the context of this problem.

### Answer:
The number of additional subscriptions is \( x = -1,216 \).

Here are some related questions for deeper understanding:

1. How do you interpret negative values in a subscription-based equation?
2. Can this result apply to situations involving inventory rather than subscriptions?
3. How would the equation change if the subscription rate changes from 55 to 60?
4. What happens to the solution if the total number of sales increases?
5. Can you set up a similar equation if the fixed subscription numbers were unknown?

**Tip:** Always double-check your total when working with large values to avoid calculation errors.
