Newspaper and soft drink are priced almost the same around $1 per unit by vending machines. Given the same unit price (value), how come a newspaper vending machine can be opened easily (i.e. take as many as you want) but a Coke vending machine is tough to open (i.e. drop one can at a time)? Please discuss it by marginal analysis for optimization.
