If Terry earns a $250 salary plus $5 per sale, he has to make 3 sales to earn $765.

Explanation:

With every sale, Terry earns $250 plus $5. So, if he earns $765 altogether, a division of 765 / (250 + 5) must be made.

So, according to this reasoning, as 765/255 is 3, that is the amount of sales that Terry must make to earn $765.
