Calculating the Number of Fish Bought

To calculate the number of fish bought, we can use the information provided in the question. Let's break it down step by step.

1. Initial Number of Fish in the Tank: - Initially, Dasha had 3 aquarium fish. - They bought additional fish. - After adding the new fish, there were 5 fish left in the tank.

2. Calculating the Number of Fish Bought: - Let's assume the number of fish bought is represented by the variable 'x'. - The total number of fish after buying more fish can be represented as: 3 (initial fish) + x (fish bought) = 3 + x. - After putting 4 fish in the tank, there were 5 fish left, so the equation becomes: 3 + x - 4 = 5.

3. Solving for x: - Solving the equation 3 + x - 4 = 5 will give us the value of x, which represents the number of fish bought.

   3 + x - 4 = 5
   x - 1 = 5
   x = 5 + 1
   x = 6
   

Conclusion

Dasha bought 6 fish to add to the aquarium.
