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 bottles she needs to sell to earn $100. 1. 25x 1. 49 = 100 What error did Barbara make in writing the equation?.

Answer 1

Solving a linear inequality is comparable to solving a linear equation because the goals of both are the same, namely to obtain the variable alone.

The right answer, option D, is The Barbara equation did not take into account the number of bottles of water.

Given:

The cost of a bottle of iced tea is $1.49.

The cost of a bottle of water is $1.25.

Barbara created the equation:

$1.25x+1.49=100$

In this question, Barbara multiplies the bottle's selling price by the number of bottles using the coefficient x.

However, she did not apply any coefficient to the bottle of water.

The right equation is:

$1.25x+1.49y =100$

where y is the number of water bottles sold to make a $100 profit.

As a result, the right answer is that the Barbara calculation did not take into account the number of bottles of water.
