The Backstory After walking for 2 days, 7 hours, 27 minutes and about 36 seconds, Don Ramon and el chavofinally made ittoAcapulco. Needless to say thatthey are excited and want to explore the city and buy food andsouvenirs. Unfortunately, things are not quite as straightforward as in Mexico city. For starters, prices are listed in foreign currencies, and for some reason stores do not listthe unit price of a product. El chavo wants to buy his favorite food "torta de jamon' (ham sandwich), and while one store has the item listed as4 tortas 20 dollars, another one lists the same item as 5tortas 15 euros. Since they are already short on cash they do not want to spend more money than what they should. They could try figuring out the conversions and unit prices but as you know, they are not very good with math. Y ahora, quin podra ayudarlos? (who can help them now?).
