Final answer:
The cost of 12 tokens is $4.80.
Step-by-step explanation:
This question is related to a budget constraint problem. The given information is not directly related to the question about the cost of 12 tokens. However, we can assume that the cost of 12 tokens is proportional to the total cost of 30 tokens. We can set up a proportion to solve for the cost of 12 tokens:
30 tokens = $12
12 tokens = (12/30) x $12 = $4.80
Therefore, the cost of 12 tokens is $4.80.
