In this situation, the domain refers to the possible number of party favors that can be bought, while the range refers to the total cost of the party favors.
Domain: The number of party favors can be any non-negative integer, as it is reasonable to buy at least one party favor (0 is also a possibility if no favors are desired) and there are no restrictions on the maximum number.
Range: The total cost of the party favors should not exceed $30. Therefore, the range for this situation is a non-negative real number that is less than or equal to $30.
Domain: x ∈ [0, ∞) or x ≥ 0 (non-negative integers)
Range: y ∈ [0, $30] or y ≥ 0 (non-negative real numbers)
You are buying party favors that cost $2.47 each.
You can spend no more than $30 on the party favors.
What domain and range are reasonable for this situation?
