Final answer:
The average American household spends roughly one-third of their consumption on housing and food/vehicle expenses combined, making the correct answer to the percentage of personal income spent specifically on food about 15-20%.
Step-by-step explanation:
The average American spends a significant portion of their personal income on food. According to the U.S. Bureau of Labor Statistics' Consumer Expenditure Survey, the average U.S. household spent roughly one-third of its consumption on both shelter and food/vehicle expenses combined. Since one-third of consumption is for food and vehicle expenses together, and considering the variation depending on family income, geography, and preferences, the percentage spent specifically on food is actually less than one-third. The correct answer would be B) 15-20%.
