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?
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)
