B. Barbara's equation did not consider the number of bottles of iced tea. She only put 1.49, which would mean she only sold one. Because we know she sells more then one, it should be 1.49(then a variable)

Answer:

B = Barbara’s equation did not consider the number of bottles of iced tea.

Step-by-step explanation:

Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle.

Let the water bottles she needs to sell be = x

Let the iced tea she needs to sell be = y

As she wants $100, she has to sell the following numbers of drinks.

1.25x+1.49y=100

----------------------------------------------------------------------------------------------

But, Barbara wrote an equation 1.25x+1.49= 100

She did not put a variable with 1.49, that will depict the number of iced teas she needs to sell.

Hence, option B is correct.
