Final answer:
The function rule that gives the total cost of apples in terms of the number of pounds, x, can be represented as: Total cost of apples = x * cost per pound of apples. Using the information provided, we know that 10 apples cost $5.00 in 2001. Therefore, the cost per pound of apples is $0.50. So, the function rule can be written as: Total cost of apples = 0.50 * x.
