Suppose Julia made x dollars in 2015, and Anna made y dollars.
in 2016, Julia made (x+30,000) and Anna made (y+10,000)
In 2016, after they paid 50% tax, they still had 80,000, which means before tax they had a total of 160,000, so
(x+30,000)+(y+10,000)=160,000
simplify: x+y=120,000
in 2015, Julia earned 20,000 more than Anna, so x=y+20,000. Plug it in the above equation: y+20,000+y=120,000
y=50,000
x=y+20,000=70,000
Julia made 70,000 dollars in 2015.

15²-9²= x² use Pythagoras' theorum and square the two smaller sides to get the square of the hypotenuse (the diagonal) then rearrange this to get the above calculation
17 is next in the pattern
