To find the total number of scoops purchased by 500 students at a price of $2.00 per scoop, we can use the demand equation given in the graph:

Q = 100 - 10P

Where Q is the quantity demanded (in scoops) and P is the price per scoop (in dollars).

At a price of $2.00 per scoop, we have:

Q = 100 - 10(2) 
Q = 100 - 20 
Q = 80

This means that each student purchases 80/5 = 16 scoops per week (since there are 5 days in a typical school week).

To find the total number of scoops purchased by all 500 students, we simply multiply the number of scoops per student by the number of students:

Total Scoops = 16 scoops/student x 500 students 
Total Scoops = 8,000 scoops

Therefore, the answer is C) 3,000.
