Question 299190: The science club consisting of 2 adults and 8 students went to the city park to plant trees. Each adult planted z trees and each student planted 1 tree. all together, the group planted at least 12 trees.
How do you write an inequality to express this situation?

There are 2 adults who plant 'z' trees. So there are 2z trees that have been planted by adults total. Because there are 8 students and they each plant a single tree, this means that there are 8%2A1=8 trees planted by students total. In total, the club has planted 2z%2B8 trees


Now since "the group planted at least 12 trees" (at least being the key word here), this means that they planted 12 or more trees. So the inequality is 2z%2B8%3E=12. I'll leave it to you to solve it.
