109 students like Reese's Peanut Butter Cups or Snickers, but not Twix.
Step-by-step explanation:

How many students like Reese's Peanut Butter Cups or Snickers, but not Twix?

19 like all three kinds of chocolate candy. This means that
31 like Snickers and Reese's Peanut Butter Cups: This means that
82 like Twix and Reese's Peanut Butter Cups
70 like Snickers and Twix
134 like Reese's Peanut Butter Cups
149 like Snickers
How many students like Reese's Peanut Butter Cups or Snickers, but not Twix?
109 students like Reese's Peanut Butter Cups or Snickers, but not Twix.
