Max would be equal to 10. If the min is equal to six, and instead of colons, I'm going to write an equal sign. If the min is equal to six, then the max at most can be equal to 10. And we can't take a higher min because we know that the six is going to be one of the values. We could try a lower minimum value. We could say the minimum value is five or four or three or two or one, but then the maximum would go down even more because remember, the maximum is no more than four larger than the minimum. So if we assume six, and we know that one of the salespeople sold six cars, then the maximum that any of the salespeople could have sold is 10.
