Let Jane's share = x
Equation
5:3 :: x:(x - 16)
5/3 = x / (x - 16)
Solve
Cross multiply
5*(x - 16) = 3*x
5x - 80 = 3x Add 80 to both sides.
5x = 3x + 80 Subtract 3x from both sides.
5x - 3x = 80
2x = 80 Divide by 2
x = 80/2
x = 40
So Jane's share is 40 dollars and Ken's is 40 - 16 = 24 dollars<<< Answer
