Answer

Brief Explanations:

The total earnings should be the sum of the money from selling water and iced - tea. If $x$ is the number of bottles of water, the money from water is $1.25x$. But the money from iced - tea should be a term like $1.49y$ where $y$ is the number of bottles of iced - tea. In Barbara's equation $1.25x + 1.49=100$, she only has a single non - variable term for iced - tea price instead of a term representing the total money from iced - tea sales based on the number of bottles sold. So, she did not consider the number of bottles of iced tea.

Answer:

Barbara's equation did not consider the number of bottles of iced tea.
