Respuesta :

Since she is selling 1.49 per iced tea bottle, and 1.25 per water bottle, and she only consitered how many water bottles she would sell, and not iced tea bottle, the awnser would be: "Barbara's equation did not consider the number of iced tea drinks."
the equation did not account for the number of iced tea drinks.

it should be:
let x = number of water drinks.
let y = number of ice tea drinks.

1.25x + 1.49y = 100
