C) Which of the items had the greatest increase in sales over the 3 years ? Give a reason for your answer
1 answer:
Answer: Tablets because they increase in sales by 467%
Step-by-step explanation:
The item with the greatest increase is the one that has the highest percentage increase in the 3 years.
Each box represents 20 units sold.
Desktop Computers:
= (2017 sales - 2015 sales) / 2015 sales * 100%
= (160 - 100) / 100 * 100%
= 60%
Laptops:
= (280 - 160) / 160 * 100%
= 75%
Tablets:
= (340 - 60) / 60 * 100%
= 467%
