L has "x -3"
S has "x"
x + x - 3 = 17
2x -3 (+3) = 17 (+3)
2x = 20
2x/2 = 20/2
x = 10
Leona has x - 3, or 10 - 3, or 7 dollars
Skye has 10 dollars
hope this helps
the constant of variation or namely its slope will be

Look at the table and find the X value for when both f(x) and g(x) are the same,
They are the same when X is -1 and when x is 0
The two answers would be X = -1 and x = 0
A graphing calculator can do a linear regression on these points very easily. The y-intercept is 107.

If you want to do this by hand, you can use the 2-point form of the equation for a line, then evaluate for x=0.
.. y = (100 -102)/(35 -25)*(x -25) +102
.. y =-2/10*(0 -25) +102
.. y = 107
