Answer:
Barbara’s equation did not consider the number of bottles of iced tea.
Step-by-step explanation:
She made this error because she included 1.25 with the x variable but did not include the x variable next to 1.49.
The x variable is important because it can keep track of how many bottles were sold of each water and tea.
So, this means Barbara’s equation did not consider the number of bottles of iced tea.
The real equations should be 1.25x + 1.49x = 100
Hope this Helps!
