Question

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 drinks she needs to sell to earn $100. 1.25x + 1.49 = 100 What error did Barbara make in writing the equation?

Answer 1

She had not taken other variable for number of iced tea may be Y.
Therefore the equation should be
1.25x + 1.49y = 100

Answer 2

Thank you for asking this question. Here is your answer:

We can conclude this hat She made $1.49 at a fixed rate.

And also that she sold only 1 bottle.

She needed to add x amount in the  1.49 to show ow many iced tea bottles she sold in actual.

So we can write it as:

1.25x = 1.49y

=100

So 100 is the final answer for this question.
