Question

1. To make a peanut butter and jelly sandwich, you need 2 slices of bread, 2 tablespoons of peanut

butter, and 1 tablespoon of jelly. You have 6 slices of bread, 12 tablespoons of peanut butter,
and 4 tablespoons of jelly. How many whole sandwiches can you make, and what is the limiting
ingredient?
a. 4, jelly
b. 6, peanut butter
c. 3, bread
d. 4, bread
e. 3, peanut butter

Answer 1

The limiting ingredient for making peanut butter and jelly sandwiches is bread, which only allows for 3 sandwiches to be made with the provided ingredients.

Step-by-step explanation:

To determine how many whole peanut butter and jelly sandwiches one can make with 6 slices of bread, 12 tablespoons of peanut butter, and 4 tablespoons of jelly, we need to find the limiting ingredient. Each sandwich requires 2 slices of bread, 2 tablespoons of peanut butter, and 1 tablespoon of jelly. By dividing the ingredients you have by the amount needed for one sandwich, you can determine how many sandwiches you can make with each ingredient:

Bread: 6 slices ÷ 2 slices per sandwich = 3 sandwiches

Peanut Butter: 12 tablespoons ÷ 2 tablespoons per sandwich = 6 sandwiches

Jelly: 4 tablespoons ÷ 1 tablespoon per sandwich = 4 sandwiches

Since the number of sandwiches is limited by the ingredient you run out of first, in this case, it is the bread that limits the number of sandwiches to 3. Thus, the correct answer is option (c) 3, bread.

Answer 2

3, bread

Step-by-step explanation:

bread is the limiting reagent because it is what you have the least of recipe wise. you would be able to make 4 sandwiches if there were 8 slices of bread, then the limiting reagent would be both the bread, and jelly, leaving the bread as the excess reagent.
