Is the word "dollars" after 25 not supposed to be there? – Ross Millikan Oct 19 '12 at 13:03

Removing the word "dollars" from the question, it looks like there were a total of $25$ radios sold. If there were $x$ sold at $\$87$ and $y$ sold at $\$119$, the total income was $87x+119y$. This gives $x+y=25, 87x+119y=2495$
