This consumer has experienced Response: no change in purchasing power. * Edit Question 2 Suppose the price of is PhP20 and the price of is PhP10 and that good is plotted on the horizontal axis. If the price of doubles and the price of triples, leaving the consumer’s income unchanged, the budget line Response: will shift out from the origin. * Edit Question 3 7Evaluate the truthfulness of the following statements. I. All points to the interior of the budget constraint are affordable. II. All points that lie on the budget constraint cost the same amount of money.…show more content…
* Edit Question 19 The tangency condition for the optimal choice for a consumer is given by Response: MUx/MUy = Py/Px * Edit Question 20 The marginal utility of the first cup of coffee that Bessie drinks in the morning is worth \$2.00. The marginal utility of the 9th cup of coffee he drinks is positive while the marginal utility of the 10th cup of coffee he drinks in the morning is worth \$0. This implies that at a price of \$0, Tom would drink Response: zero cups of coffee per morning. * Edit Question 21 Sergy can buy either pizzas or submarine sandwiches.

If good is plotted on the horizontal axis, the budget line Response: will shift out from the origin parallel to the original budget line. * Edit Question 24 At a consumer’s optimum combination, which of the following will not necessarily hold
