1. We are asked to find the sum of the list of prices. 2. Add all values starting with the first line values: $$400+200+200+200+200+200+200+1500+200+200+200+200+200+200+200+200+200+200+400+400+400+200+200+200+200+200+200+200+200+200+200+200+800=8900$$ 3. Add the second line values: $$400+400+400+200+400+200+200+200+200+200+200+400+200+200+200+200+200+200+200+200+200+200=6200$$ 4. Add the third line value: $$200$$ 5. Add the fourth line values: $$200+400+400+200+200+200=1600$$ 6. Finally, sum all totals: $$8900+6200+200+1600=16900$$ 7. The total sum of the prices is $$16900$$.
