Final answer:
To determine the greatest number of sandwiches Jai and Reena can make, we need to find the limiting reactant. The limiting reactant is the ingredient that will run out first and will determine the maximum number of sandwiches that can be made.
Step-by-step explanation:
In order to determine the greatest number of sandwiches Jai and Reena can make, we need to find the limiting reactant. The limiting reactant is the ingredient that will run out first and will determine the maximum number of sandwiches that can be made.
Given that there are 42 cheese slices, 63 apple slices, and 84 tomato slices, let's find how many sandwiches can be made using each ingredient:
1 sandwich = 1 slice of cheese + 1 slice of apple + 1 slice of tomato
Using the available ingredients, the maximum number of sandwiches that can be made is determined by the lowest quantity of any ingredient. In this case, there are 42 cheese slices, so a maximum of 42 sandwiches can be made.
