Answer:
Yes
Step-by-step explanation:
Yes, this concept is an example of supply and demand. When there is a limited supply of a product like the soft drinks in the vending machines then the price would match the number of people that want to buy the product. If in a very hot day more people want to buy a soft drink to cool down then the supply will begin to decrease as more people buy, this will create an increase in price as people would be ok with paying more money in order to be one of the lucky few to get one of the few soft drinks that are left.
