Final answer:
The possible domain values are all weights less than or equal to 2.5 pounds, and the possible range values are all costs obtained by multiplying the weight by $1.80.
Step-by-step explanation:
The possible domain values for this situation are the weight of the bulk candy that a customer can purchase, which in this case is restricted to at most 2.5 pounds. So, the domain values would be all the weights less than or equal to 2.5 pounds.
The possible range values for this situation are the cost of the candy, which in this case is sold for $1.80 per pound. So, the range values would be all the costs obtained by multiplying the weight by $1.80.
Therefore, the possible domain values are all the weights less than or equal to 2.5 pounds, and the possible range values are all the costs obtained by multiplying the weight by $1.80.
