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?

Step-by-step explanation:

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 need to sell to earn $100 as

1.25x + 1.49 = 100

In this equation Barbara has assumed the number of water bottle sold as x but she hasn't assumed another variable for the bottles sold of iced tea,

Therefore, Barbara should take two variables one for the number of bottles sold of water and another for the bottles sold of iced tea.

Equation should be in the form of

1.25x + 1.49y = 100

$35.59 in pounds
