Answer:
c. a representative collection of goods and services.
Step-by-step explanation:
The market basket acts as a representative collection of goods available to all consumers. This is for economists to do analyzes such as calculating inflation and consumer welfare. For example, if a representative basket cost $ 100 in 2018, but in 2019 it costs $ 110, that means inflation, as the same products now cost more, and consumers' purchasing power declined, because in 2018 they had to spend only $ 100 to buy that basket of products, but now you have to spend $ 110. On the contrary, if the price of the basket of goods decreases over time, it is a sign that consumers have been better off, because before they spent $ 100 and now spend less, that is, there would be increased purchasing power. This is also a sign that there has been economic deflation, which is the continuing and widespread fall in price levels.
