Jesse and her brothers nick and owen are saving money over the summer each week, jesse saves twice as much as owen. Owen saves $
Harrizon [31]
If how much owen saves is x, 2x=y (jessie's amount of saved money) and
 x-5=nick's amount of money =z

Since x+y+z=220, we plug 2x in for y and x-5 in for z, getting x+2x+x-5=220. Adding 5 to both sides, we get 4x=225 and by dividing by 4 we get x=225/4=61.25 dollars. 61.25-5=56.25=z=nick's money, and 61.25*2=122.5=jessie's saved money
