Celia bought a bag of 12 goldfish for $3dollar sign,

What is the cost of 1 goldfish?

The cost is $0.25 per goldfish.

Step-by-step explanation:

$3/12=$0.25

The correct answer is $0.25

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.
