balloons.
To find the value of n, we can subtract the number of balloons popped by Krista from the total number of balloons popped by both Krista and Alexa:
Total balloons popped by both = 13 balloons
Balloons popped by Krista = 5 balloons
Balloons popped by Alexa = Total balloons popped by both - Balloons popped by Krista
= 13 balloons - 5 balloons
= 8 balloons
Therefore, Alexa popped 8 balloons.
