Answer:
The correct answer is $0.25
Step-by-step explanation:
The first thing we should do in this exercise is to analyze the information we have.
If we know that a bag with a total of 12 goldfish costs 3 dollars, we must know that to find out the price of each goldfish we must divide the final price by the total goldfish.
So 12: 3 = 0.25
In this way we can verify that the correct answer is 0.25.
