Final answer:
To determine how many people Brian's farm can feed, divide the total area of the farm by the average number of square feet required to feed one person.
Step-by-step explanation:
To determine how many people Brian's farm can feed, we need to divide the total area of the farm by the average number of square feet required to feed one person.
Let's assume the average number of square feet required to feed one person is 100 square feet. To find the number of people Brian's farm can feed, we divide the total area of the farm (75,000 square feet) by the average number of square feet required per person (100 square feet).
Number of people Brian's farm can feed = Total area of the farm / Average number of square feet required per person = 75,000 square feet / 100 square feet = 750 people.
