Tim Horton’s is a Canadian fast-food chain, a sort of combination of Dunkin’ Donuts and McDonald’s in the United States. I took this photo during a summer trip because I was interested in the pattern of servings and prices. I hope you will be, too. Here’s what I was thinking while standing in line . . . 1. Let’s ignore the price-ending-in-9-to-make-it seem-like-you’re-getting-a-good-deal nonsense and round up to the nearest dime to make it easier to think about. How much are hungry Canadians (and one old, fat American) paying per TimBit in the 10 pack, 20 pack, and 40 pack? This is called unit pricing.
2. There are a 10 pack, a 20 pack, and a 40 pack on the poster. Suppose Tim Horton’s offers the next two logical sizes in the pattern. How many TimBits will the next two packs hold? 3. Based on the two sizes you have created and the price pattern for the first three sizes, what would be the prices of the two larger packs you have created? Extra Credit: The BIG math philosophical question: If this pattern continues--the packs getting larger, the unit price getting smaller--how many TimBits would you get for free? This seems like a line graph or bar chart might be helpful . . . You have the same number of pennies, nickels, and dimes in your pocket.
You have $1.44. You don’t have any other coins or bills. How many of each coin do you have? |
