Krista and Alexa played balloon darts in a school fair. Krista popped 6 balloons, which is 1 balloon less than Alexa. Complete the working equation that represents the number of balloons, b , that Alexa popped and solve the equation.

Answer 1

Let b be the number of balloons that Alexa popped.
According to the given information, Krista popped 6 balloons, which is 1 balloon less than Alexa.
This can be expressed as: b - 1 = 6.
Adding 1 to both sides of the equation, we get b = 7.
Therefore, Alexa popped 7 balloons. Answer: \boxed{7}.
