Tim takes his 3 children trick or treating. They are out for 4 hours. Each hour they visited 5 houses. Each house gives 3 treats per kid. How many treats do his children get in total? Think carefully first, then make a decision:
They visit 4 * 5 = 20 houses. That means each child get 20 * 3 = 60 treats. So in total they get 60 * 3 = 180 treats. So, the answer is 180.
