Carrie's company is dealing with a mixed economy.
Step-by-step explanation:
Mixed economy is that type of economic system where the laws of demand and supply direct the production and the consumption of the goods and the services in the market along with the intervention of the government in the business. This means that with the increase in the price, the demand of the good falls and vice versa.
So in this company, with the tax exemption from the government, there is fall in the price of production, leading to increase in the demand because of the fall of price of the goods. So there is a mixed economy.
