Answer: increases by $220.
Step-by-step explanation:
The gross domestic product simply means the value in terms of money of the goods that are produced by a particular economy.
Based on the information given in the question, we are told that the household purchase a $40 pair of shoes made in Thailand by a Thai firm, a $1240 television made by a Korean firm in Korea, and $220 on groceries from a local store.
We should note that the GDP will increase by $220 because the groceries were produced in the United States while the other purchase doesn't add to the GDP as they are from other countries.
