A: K = J + 2,000 - no help.
B: with p% increase for each of them, Karen will make $2440 more than Jason
K(1 + p/100) = J (1 + p/100) + 2440 - no help, you still have too many variables.
Together:
Substitute (J + 2000) for K in the second equation.
(J + 2000)(1 + p/100) = J (1 + p/100) + 2440
then: J(1+ p/100) + 2000 (1 + p/100) = J(1+ p/100) + 2400.
subtract J(1 + p/100) from each side you get
2000 (1+p/100) = 2440
p = 22%
