Word math problems are a great way to engage students in learning how to apply the skills they have learned. Interesting problems encourage students to think creatively about how to solve problems that have applications in the real world.
Both in 2020 and 1920, there were many word problems that are based on food-related topics. However, there are major differences in the problems. Based on a quick scan of food-related problems on Pinterest, restaurant menu, food truck, pizza fraction, and food cost problems are currently popular. Food-related math problems in a 1920 home economics textbook also addressed cost, but with a slight twist. The focus of these hundred-year-old problems was on how to get a given number of calories for the least cost.
- A quart of milk gives 675 calories; a pound of lamb chops, 1600; a pound of eggs (eight or nine), according to size, 670 calories. With milk at 17 cents a quart, lamb chops at 48 cents a pound, and eggs at 60 cents a dozen, which food is the cheapest per 100-calorie portion?
- Cream of wheat has a fuel value of about 1600 calories and costs 15 cents a pound. Compare the cost of a 100-calorie portion of cereal with that of chops, milk, or eggs.
- Large oranges cost 60 cents per dozen. What is the cost of a standard portion?
- A good juicy apple yields about 100 calories. Dried apples give about 1320 calories per pound Find the difference in cost of 100-calorie portions, if fresh apples sell at the rate of 3 for 10 cents and dried apples cost 15 cents a pound.
