i. A consumer has income of $3,000. Wine costs $3 per glass, and cheese costs $6 per pound. Draw the consumer's budget constraint with wine on the vertical axis. What is the slope of this budget constraint? ii. Show a consumer's budget constraint and indifference curves for wine and cheese. Show the optimal consumption choice. If the price of wine is $3 per glass and the price of cheese is $6 per pound, what is the marginal rate of substitution at this optimum?
