Tаke а clоse lооk аt the table below with data from the University of Pennsylvania showing the amount of money that different income groups spent on food in 2020. (The 0-20 Income Group makes the least amount of money annually, while the 95+ group makes the most.) Calculate the percentage of total annual spending that each income group spends on food and add record your calculations on a table on your scratch paper.What do you notice about the percentage of each group’s total annual spending on food? Based on this data, what income percentile might feel the impact of inflation the most? Why? Return to the excerpt you read at the beginning of Part 3A. How might these numbers explain why, to a high-income suburban mom, inflation is “just annoying,” and to poorer families, “the difference can mean hunger”?
