hard word problem

You have quarters and dimes that total $2.80. Your friend says it is possible that the number of quarters is 8 more than the number of dimes. Is your friend correct?    

The way the problem is worded, the number of quarters has to be exactly 8 more than the number of dimes. 

To have 8 more quarters than dimes, you have to have at least 9 quarters, so let's start with that many. 

                       No. Quarters   No. Dimes   Total of $  

                                 9                 1                2.35  

                               10                 2                2.70  

                               11                 3                3.05   

So I say it is NOT POSSIBLE.  What say you?
