Fido weighs 26 pounds more than Fifi. Fifi weighs 12 pounds less than Rover. If the sum of their weights is 71 pounds, how much does Fifi weigh?

To find Fifi's weight, let's set up the relationships based on the information given in the question.

1. Let Fifi's weight be represented as F.

2. According to the question, Fido weighs 26 pounds more than Fifi, so Fido's weight can be represented as F + 26.

3. Fifi weighs 12 pounds less than Rover. If we let Rover's weight be represented as R, then Rover's weight can be described as F + 12.

Now, the total weight of Fido, Fifi, and Rover can be expressed with the equation:

(F + 26) + F + (F + 12) = 71.

Combining the weights results in:

3F + 38 = 71.

From here, you can solve for F:

3F = 71 - 38,

3F = 33,

F = 33 / 3,

F = 11.

This calculation shows that Fifi weighs 11 pounds. The correct choice corresponds to this solution, indicating that Fifi's weight is indeed 11 pounds, confirming the accuracy of this conclusion.
