Final answer:
After giving away 6 pounds of clay, Mateo has 12 pounds left, which allows him to make 36 bags of 1/3 pound each.
Step-by-step explanation:
When Mateo buys 18 pounds of clay and gives away 6 pounds, he is left with 18 - 6 = 12 pounds of clay.
To determine how many 1/3 pound bags Mateo can make, we divide the remaining clay by the weight of each bag.
So, 12 pounds divided by 1/3 pound per bag equals 36 bags.
Mateo can make 36 of the 1/3 pound bags of clay.
Therefore, the correct answer is d) 36.
