Ask Marilyn: Which Is the Best Pizza Deal?
Michael Paul Storey of Kingston, Washington, writes:
Marilyn: A woman goes to a restaurant and orders a 12-inch pizza for $10. The waiter says the 15-inch pie for $15 is a better deal. But $15 is 50 percent more than $10; 15 inches is only 25 percent more than 12 inches. Is the bigger pizza really a better buy?
Not necessarily. A 12-inch pie contains about 113 square inches of pizza; a 15-inch pie has about 177 square inches. That makes the larger pizza a little cheaper per bite. (About 8.5 cents versus 8.8 cents per square inch.) But is that a better deal overall? Nope—if the woman orders the bigger pizza, she’ll spend more money and consume more calories than she intended.
