Final answer:
The statement that a store of value can preserve economic value for future expenditure is true, with money being a common example despite the possibility of inflation.
Step-by-step explanation:
A store of value is indeed something that serves as a way of preserving economic value that can be spent or consumed in the future. This is a true statement. A simple example is the concept of money in the economy. While in a barter system, goods like shoes might decrease in value over time due to factors like going out of style, money generally retains its value and is a more reliable means of storing value. Money may not be a perfect store of value due to inflation which causes it to lose some buying power over time, but it still serves this function as it remains money.
