Question

How much people picked salt and vinegar?

Answer 1

80(36°/360°) = 80(.1) = 8 people picked salt and vinegar.

Answer 2

8 people

Explanation:

Given:

• Total people = 80
• People who choose Salt and vinegar in pie chart = 36°

To find:

• People who choose Salt and vinegar.

Solution:

To find the number of people who choose Salt and vinegar, we need to calculate the percentage of the pie chart that is represented by the Salt and vinegar slice.

`\begin{aligned} \sf \textsf{Percentage of pie chart } & = (36^\circ)/(360^\circ)\cdot 100\% \\\\ & = 10\% \end{aligned}`

Therefore, 10% of the 80 people chose Salt and vinegar.

Number of people who chose Salt and vinegar

= 10% of 80 people

= 0.1 × 80 people

= 8 people

Therefore, 8 people picked salt and vinegar.
