Ms.Sue when you answered my question you said x= 3.87 but then the daughters drink would be $2.97 and the sons drink would be $5.97 not 6.07 and the total wouldnt add up to $12.90, it would add up to 12.81.... i don't get this

Here's your original question.
My family went to starbucks. We ordered 3 drinks. My daughter's drink was .90 cents less than my drink and my sons drink was $2.20 more than my drink. The total bill was $12.90. How much was each drink? Use algebra.
3.87 + 2.20 = 6.07 
no it wasn't 2.20 it was 2.10

i miss typed its actuallt 2.10 not 2.20
im still stuck 
Go back and do the problem the way I did  but use the correct numbers.

ok thanks, and its totally my fault cause i miss typed the question. thank you for understanding and helping me :)

You're welcome. :)
