We would expect an increase in the price of pizza to: O reduce the demand for both soda and tacos. reduce the demand for soda and increase the demand for tacos. increase the demand for both soda and tacos. O reduce the demand for tacos and increase the demand for sodas.arrow_forwardTwo students, Nick and Sofia, are discussing normal and inferior goods. Nick says that if Frodo buys more beer when the price of beer goes up, then beer must be an inferior good for Frodo. If, on the other hand, he buys less beer when the price of beer goes up, then beer must be a normal good for Frodo. Sofia disagrees: "Normal and inferior goods are about income changes, not price changes. Therefore, we do not have enough information: beer could be an inferior or normal good in either of these cases." Do you agree or disagree? Carefully explain your point of view. Support your argument with graphs of income, substitution and total effects (please put beer on the horizontal axis and the other goods on the vertical axis). Please assume that Frodo's preferences over beer and other goods are strictly convex and satisfy "more is better" assumption.arrow_forward
- Suppose you have $12 to buy apples or oranges. The price of both apples and oranges is $2, and the marginal utility of buying apples or oranges is shown in the following table: a. In equilibrium, how many apples and oranges would you buy? b. Please speculate and draw the demand curve for apples or oranges (Note: the demand curve depicts the function of price and quantity demanded).arrow_forwardInfo in imagesarrow_forwardSuppose that you discover that, ceteris paribus, when the price of tomatoes increases, the demand for bleu cheese decreases. From this you conclude that: tomatoes and blue cheese are substitutes. tomatoes are inferior goods and blue cheese is a normal good. tomatoes and blue cheese are complements. the demand curve for tomatoes has shifted to the left.arrow_forward
