Analyzing Battery Sales Data: Finding Continuous Decrease
The question asks us to identify which type of battery experienced a continuous decrease in sales from the year 2015 to the year 2020, based on the provided table of sales figures (in thousands) for five different types of batteries sold between 2015 and 2021.
| Year | Types Of Batteries Sold (in thousands) | ||||
|---|---|---|---|---|---|
| 4AH | 7AH | 32AH | 35AH | 55AH | |
| 2015 | 75 | 144 | 114 | 102 | 108 |

| 2021 | 115 | 85 | 160 | 100 | 145 |
Checking Sales Trends from 2015 to 2020
To find the battery type with continuous decrease in sales from 2015 to 2020, we need to look at the sales figures for each type year by year within this period and check if each subsequent year's sale is less than the previous year's sale.
- 4AH battery sales:
- 2015: 75
- 2016: 90 (Increase from 2015)
Sales did not continuously decrease from 2015.
- 7AH battery sales:
- 2015: 144
- 2016: 126 (Decrease from 2015: 144 > 126)
- 2017: 114 (Decrease from 2016: 126 > 114)
- 2018: 90 (Decrease from 2017: 114 > 90)
- 2019: 75 (Decrease from 2018: 90 > 75)
- 2020: 60 (Decrease from 2019: 75 > 60)
Sales continuously decreased from 2015 to 2020 for the 7AH battery.
- 32AH battery sales:
- 2015: 114
- 2016: 102 (Decrease from 2015)
- 2017: 75 (Decrease from 2016)
- 2018: 150 (Increase from 2017)
Sales did not continuously decrease from 2015.
- 35AH battery sales:
- 2015: 102
- 2016: 84 (Decrease from 2015)
- 2017: 105 (Increase from 2016)
Sales did not continuously decrease from 2015.
- 55AH battery sales:
- 2015: 108
- 2016: 126 (Increase from 2015)
Sales did not continuously decrease from 2015.
Based on the analysis of the sales figures from 2015 to 2020, only the 7AH battery type shows a continuous decrease in sales during this period.
Conclusion on Continuous Sales Decrease
The sales figures for the 7AH battery type were 144 (2015), 126 (2016), 114 (2017), 90 (2018), 75 (2019), and 60 (2020). Since each year's sale is less than the previous year's sale within this range, this battery type satisfies the condition of continuous decrease in sales from 2015 to 2020.

Additional Information: Data Interpretation Basics
Interpreting data from tables like this involves carefully reading the rows and columns to extract specific information. When looking for trends, it's important to compare consecutive values over the specified period. A 'continuous decrease' means that the value in year \(n+1\) must be strictly less than the value in year \(n\), for all years \(n\) within the defined range (2015 to 2019 in this case, comparing up to 2020 sales).
This type of question tests your ability to extract, compare, and analyze numerical data presented in a structured format.
