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.
The equation that represents the number of balloons that Alexa popped is: b - 1 = 6.
Solving the equation, we add 1 to both sides: b = 6 + 1.
Therefore, Alexa popped a total of 7 balloons. Answer: \boxed{7}.
