The turtle tank has 24 yellow turtles, computed using the guess and check method.
What is the guess and check method?
The guess and check method is the process of guessing a solution to the given conditions that will be satisfying all the conditions.
How to solve the question?
In the question, we are informed that Bernadette is at the turtle tank, which has 32 green and yellow turtles in the tank. We are also informed that there are 3 times as many yellow turtles as green turtles.
Assuming the number of green turtles to be g, and the number of yellow turtles to be y, we can write the equation g + y = 32, as the total number of turtles is given to be 32.
Now, we are told that the number of yellow turtles is 3 times the number of yellow turtles.
Thus, we can say that y = 3g.
Substituting this in the equation, we get g + 3g = 32, or, 4g = 32.
We are asked to solve this equation by the guess and check method.
If we guess g to be 7, the equation is not satisfied as we get 28 = 32.
If we guess g to be 9, the equation is not satisfied as we get 36 = 32.
If we guess g to be 8, the equation is satisfied as we get 32 = 32.
Thus, the correct value for g is 8.
Thus, y = 3g = 3*8 = 24.
Thus, the turtle tank has 24 yellow turtles, computed using the guess and check method.
