Smith's balloon is an algebraic expression
The expression that represents how many Balloons Smith has is p + 20
<h3>How to determine the number of ballons?</h3>
The given parameters are:
Small = p
Big = 20
Add the number of small and big ballons to get the total number of ballons
Total = Small + Big
This gives
Total = p + 20
Hence, the expression that represents how many Balloons Smith has is p + 20
