The marginal utility of the last bag of chips purchased is 8 utils, and each bag costs $1. In order to maximize his utility, Caesar should

Buy more soft drinks and fewer chips since he gets more marginal utility per dollar from soft drinks

Price discrimination works best when

Buyers do not have perfect information about the price

Airline companies engage in price discrimination by

Charging business customers higher prices than vacation travelers

Sellers can gain profits from price discrimination because

Charging different prices based on willingness to pay can increase revenues without increasing costs.

Assume two goods are substitutes. Ceteris paribus, a decrease in the price of one good will cause the equilibrium price of the other good to

Decrease and the equilibrium quantity of the other good to decrease

A leftward shift of the market demand curve for HDTVs, ceteris paribus, causes equilibrium price to

Decrease and the quantity to decrease

Is a way for sellers to elicit the maximum willingness to pay from buyers.

The law of diminishing marginal utility suggests that

People are willing to buy additional quantities of a good only if its price falls.

Price to increase and equilibrium quantity to increase.

Price-inelastic

Total revenue is

Quantity sold times price.

Price elasticity of demand shows how

Responsive the quantity demanded is to a change in price

Rosa will not buy an iPhone.

Price discrimination occurs when

Sellers charge two separate prices for the same product to separate consumers.

Car dealers can easily price discriminate because

Sellers negotiate a separate price agreement with each individual buyer.

There would be a shortage.

The law of diminishing marginal utility gives us a deeper understanding of the downward-sloping demand curve because

When marginal utility is high, we are willing to pay a higher price.
