Answer:
15%
Step-by-step explanation:
First add together the percentages that have been shown to you. It should look like this:
35+25+15+10=85
Know that every pie chart must add up tp 100%, and this is only 85%. We should subtract the 85% we have from 100%. It should look like this:
100-85=15
Therefore, 15% is your answer.
