Question

You're making sandwiches for a large crowd. All must be identical and must contain 2 slices of bread, 2 teaspoons mustard, 3 slices of salami, 3 slices of Swiss cheese, 2 lettuce leaves, 1 slice of tomato. You have on hand: 2 loaves of bread (60 slices/loaf) 3 pound of Swiss cheese 1 quart of mustard 60 slice of salami An unlimited supply of tomatoes from your garden 3 heads of lettuce, approximately 15 leaves integral each. How many sandwiches can you make? ________________ For which of the ingredients is (are) there no leftovers? ____________________ In case you've forgotten your kitchen conversions: 1 quart = 4 cups; 1 cup = 16 tablespoons; 1 tablespoon = 3 teaspoons. You like 3 teaspoons of sugar and 1/4 cup of milk in each cup of coffee, you drink. Before leaving for a trip you prepare a thermos that holds 2 quarts of liquid. What quantities of coffee, sugar and milk you use? (Assume the dissolved sugar occupies no volume.)

Explanation / Answer

First we calculate how many sandwiches can be made from available material on hand.

2 loaves of bread, 60 slices /loaf

Total number of slice = 60 x2 = 120 slices

1 sandwich contains 2 slices of bread.

From120 slices, we can make 120/2 = 60 sandwiches

3 pounds of Swiss cheese, each pound gives 16 slices

1 pound = 16 ounces

3 pounds of Swiss cheese = 3 x 16 ounces = 48 oz

1 sandwich contains 2 slices of Swiss cheese

From 48 slices of Swiss cheese, we can make 48/2 = 24 sandwiches

1 quart = 4 cups;            

1 cup = 16 tablespoons

So 4 cups = 16 x 4 = 64 tablespoons

1 tablespoon = 3 teaspoons

64 tablespoons = 64 x 3 = 192 teaspoons

1 sandwich contains 2 teaspoons mustard

From192 teaspoons, we can make 192/2 = 96 sandwiches

60 slices of salami in hand

1 sandwich contains 3 slices of salami

From 60 slices of salami, we can make 60/3 = 20 sandwiches

We have unlimited supply of tomatoes.

3 head of lettuce, approximately

15 leaves in each head

3 head of lettuce = 3 x 15 = 45 leaves lettuce

1 sandwich contains 2 lettuce leaves

From 45 leaves lettuce, we can make 45/3 = 22 sandwiches

1)We can make 20 sandwiches (From 60 slices of salami is limited in quantity, so we can make 20 sandwiches)

2)Salami is no leftovers
