Answer
Answer:
B. Barbara's equation did not consider the number of bottles of iced tea.
Explanation:
Step1: Analyze the revenue - building concept
Revenue from selling items is price per item times number of items.
Step2: Identify the correct equation structure
Let $x$ be the number of bottles of water and $y$ be the number of bottles of iced - tea. The total revenue equation should be $1.25x + 1.49y=100$. In Barbara's equation $1.25x + 1.49 = 100$, she only accounted for the price of one bottle of iced - tea instead of the price per bottle times the number of bottles of iced - tea. So she did not consider the number of bottles of iced tea.
