How do you write an algebraic expression that models the word phrase "The total height of a 1-foot tall birdbath if it is placed on a base that is b feet tall"?

Explanation:

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:

$t = 1 + b$

or

$t = b + 1$
