Final answer:
The individual can spend half an hour (30 minutes) on each chicken-stuffed pepper.
Step-by-step explanation:
To determine how much time the individual can spend on each chicken-stuffed pepper, we need to find the total time available and divide it by the number of peppers.
Given that each chicken-stuffed pepper takes twice as long as a pita bread and the individual needs to feed 3 gluten-intolerant and 8 vegetarian classmates, we can calculate the total time needed for the peppers and pita breads.
The total time needed for the peppers can be represented as 2x, where x is the time needed for a pita bread.
Let's assume the time needed for a pita bread is t. Therefore, the time needed for a chicken-stuffed pepper becomes 2t.
Since the individual needs to feed 3 gluten-intolerant and 8 vegetarian classmates, the total time needed is :
3(2t) + 8t
= 6t + 8t
= 14t.
Since the individual has 7 hours available, we can set up the equation 14t = 7 and solve for t.
Dividing both sides of the equation by 14, we find that t = 7/14
= 1/2.
Therefore, the individual can spend half an hour (30 minutes) on each chicken-stuffed pepper.
