The <u>Pie Chart</u> is the best type of chart that could be used to represent the distribution of this data.
<h3>What is a Pie Chart?</h3>
A pie chart is a type of circular statistical graph used for the representation of a data set. The graph's segments are proportionate to the percentage of the total in each group.
However, the proportion of each portion of the pie chart is proportional to the number of the group as a whole.
- The full pie chart represents 100% of the whole, whereas

Use the break even formula below. You should be able to figure it out.
Break Even = (fixed cost)/(price - variable costs)
By subtracting 25 from both sides, you get:
AB+CD-25=0
by subtracting CD from both sides, you get;
AB=25-CD
by subtracting AB from both sides, you get:
CD=-AB+25
