Q 35. If 2019 were to show the same decline as 2018 over 2017, then the total revenue in 2019 must be

Ops: A. $310,345

B. $415,059

C. $375,698

D. $345,512

To determine the total revenue in 2019, assuming the same decline as in 2018 over 2017, we need to analyze the given data carefully. Here's the step-by-step process:

1. **Identify Revenue for 2017 and 2018:**
   - Sum up the revenue from all categories (Journals, Magazines, and Books) for both 2017 and 2018.

2. **Calculate the Total Decline from 2017 to 2018:**
   - Subtract the total revenue in 2018 from the total revenue in 2017.

3. **Assume the Same Decline for 2019:**
   - Subtract the same decline from the total revenue in 2018 to estimate the revenue for 2019.

4. **Match the Estimated Revenue with the Given Options:**
   - Compare your calculated revenue for 2019 with the provided answer choices.

Let’s go through the calculations:

### Step 1: Calculate Total Revenue for 2017 and 2018
- **2017:**
  - Journals: $240,000
  - Magazines: $160,000
  - Books: $350,000
  - **Total for 2017:** $240,000 + $160,000 + $350,000 = $750,000

- **2018:**
  - Journals: $120,000
  - Magazines: $140,000
  - Books: $155,000
  - **Total for 2018:** $120,000 + $140,000 + $155,000 = $415,000

### Step 2: Calculate the Decline
- **Decline from 2017 to 2018:** 
  - $750,000 - $415,000 = $335,000

### Step 3: Estimate Revenue for 2019
- **Assumed Revenue for 2019:**
  - $415,000 - $335,000 = $80,000

### Step 4: Match with the Given Options
- None of the given options exactly match $80,000. It is possible that the problem is looking for a different kind of decline or there could be an error in the provided options.

However, based on the analysis, if we're looking for the closest possible answer with a reasonable estimate, we might have missed something, such as the actual decline pattern being different or a misinterpretation of the graph.

Please double-check the figures on the graph if possible. 

### Additional Questions:
1. What is the year-over-year percentage change in revenue from 2017 to 2018?
2. How would the revenue distribution among Journals, Magazines, and Books change if there was a 5% overall increase in 2019?
3. What factors could cause a decline in revenue similar to the one observed from 2017 to 2018?
4. If the company wants to maintain at least $500,000 in revenue in 2019, by what percentage would they need to increase sales in each category?
5. How does the decline in 2018 compare to other years not shown in the data?

### Tip:
When analyzing trends over multiple years, it's essential to look at both the absolute changes and percentage changes to understand the pattern fully.
