Hi There!
Answer: Bowler 2
Why: if you notice that line in the box plot shows the median and it specifically shows that the meadian is 20 or so greater than Bowler 1.
You're lucky that I was able to do this :)
The answer is 
Dominics son is 45inches tall
<u>Step-by-step explanation:</u>
Let his sons height be 'h'
If Dominic is 72 inches and casts a shadow of 60 inches. His son casts a shadow of 50 inches.
Then We can say that,
h = 50 x (72/60)
h = 45 inches
Dominics son is 45inches tall
It’s (x-6)(x+4) so the first one and last one
259% increase because 6 x 2 is 12 and 3 is the remainder and 3/6 is 50%
