Using the data in Extract D, calculate Nike's market share of worldwide sports footwear in 2018 - Edexcel - A-Level Business - Question 2 - 2022 - Paper 1

To calculate the total sales:

egin{align*} Total ext{ sales} &= Nike + Adidas + Asics + Puma + Under Armour + ext{Other Brands}
&= 22.3 + 14.9 + 10.7 + 2.4 + 1.0 + 16.7
&= 60.1 ext{ billion dollars} ext{(confirmed by adding the values from the chart)} ext{Total sales value of sports footwear brands in 2018 = }$60.1bn.

Nike's market share can be calculated using the formula:

$$ext{Market Share} = \left( \frac{\text{Value of Sales (Nike)}}{\text{Total Value of Sales}} \right) \times 100$$

Plugging in the numbers gives us:

$$ext{Market Share} = \left( \frac{22.3}{60.1} \right) \times 100 = 37.07\%$$

Rounded to 2 decimal places, Nike's market share is 37.07%.
