See the entire solution process below:


First, let's call the "total height" we are looking for #t#.

Then because the birdbath itself is 1-foot, the first part of the equation is:

#t = 1#

Then because we are putting it on top of a base #b# feet we need to add this to the height we already have. So we write:

#t = 1 + b#


#t = b + 1#
