Question 593890: Joh, Kevin and Jane have $120. Jane has a thied of what John has and Kevin has twice as much as Jane. How much money does, in dollars, does Kevin have? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! John, Kevin and Jane have $120.
j + k + a = 120
:
Jane has a third of what John has
a = j
or
j = 3a
:
and Kevin has twice as much as Jane.
k = 2a
:
Find how much Jane has using the 1st equation, replace j and k
3a + 2a + a = 120
6a = 120
a = 120/6
a = $20
:
How much money does, in dollars, does Kevin have?
k = 2a
k = 2(20)
k = $40
