To win the recycling contest, you must collect a total average between 83 and 87 pop tabs for 4 weeks, inclusive. Suppose you collected 82, 86, and 84 pop tabs during the first three weeks of competition. What are the possible number of pop tabs you can collect during the last week in order to win the recycling contest?

Write an inequality where X is the number of pop tabs you can collect during the last week. Then solve to find out the possible number of pop tabs you can collect.
