Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle. She wrote an equation to find the number of bottles she needs to sell to earn $100. 1.25x + 1.49 = 100What error did Barbara make in writing the equation?
Answer
A
Barbara’s equation did not consider the number of bottles of water.
B
Barbara’s equation did not consider the number of bottles of iced tea.
C
Barbara’s equation did not use the correct price for the bottles of iced tea.
D
Barbara's equation did not use the correct total for sales.
Explanation
Barbara’s equation uses x to represent the number of water bottles: 1.25x. But the $1.49 for iced tea is added only once, rather than multiplied by the number of iced tea bottles. So her equation does not account for how many iced tea bottles she sells; choice B is correct.
