In this exercise we have to calculate the values of the people who voted to expand the parking lot, so we have to:
Yes: parents will be 150 and not parents 40
No; parents will be 40 and not parents 30
As it is about sets, we have to use the data that were:
- total: 250 adults
- 180 of whom were parents a park should be expanded.
- 40 of the adults who were not parents thought the park should be expanded.
then calculate that:
[tex]250-180=70\\70-40=30[/tex]
