A scatter graph shows 10 points. The mean of the $x$-values is 7 and the mean of the $y$-values is 24. A line of best fit with gradient 2 is drawn through the mean point. The point $(16, 15)$ is then identified as an outlier and deleted. A new line of best fit, with gradient 3, is drawn through the mean point of the remaining 9 points. At what point do the two lines of best fit cross?

• A$(6, 25)$
• B$(-3, 4)$
• C$(3, 16)$
• D$(7, 24)$
