I like to set up my variables so that I know what I'm working with. We'll call short-sleeve shirt cost "s" and long-sleeve shirt cost "l." We know that:
l = 14
and 
2l + 2s = 42.40, since she bought two of each.
We can plug in l and solve for s. Hope this helps :)

You're not wrong, but if you just tell people the answer and not explain why, that will not help them on a test when a similar question comes up. You are setting people up for failure that way.

@akshay1234 Please don't give answers straight away. That's not what OpenStudy is for, that's for Yahoo Answers. @larryandfood 7.20$ (14x2 - 28) (28- 42.40 =14.40 divided by 2 = 7.20) Does that make sense?
