# Union and Intersection of Sets

Create 2 sets. Set A will be the list of the 5 items you personally need to buy the most (essential items). Set B will be the list of 5 items that you want to buy the most ( fun stuff). List the items in set A and B and also list or state the items in the union and in the intersection of set A nad B

Assume that the prices of the items in set A are 20,40,60,70 80. Assume the prices if set B are 90,120,30,60,40

What will the total cost of set A be if it contains one unit of each item? What will the total cost of the union set be if it contains one unit of each item? what will be the total cost of the intersection?

What will the total cost of the union and intersection be if you consider two sets of A's and three sets of B's?
