Question 823320
Tony is twice as old as Jon. Jon is five years older than Matt. Angie is five years older than half of Jon's age. If the sum of their ages is 180, how old is Jon?
------
Equations:
t = 2j
j = m + 5
a = (1/2)j+ + 5
t + j + m + a = 180
--------
2j + j + j-5 +(1/2)j+5 = 180
----------------------------------
(9/2)j = 180
(1/2)j = 20
j = 40 yrs (Jon's age now)
-----
t = 2j = 80 (Tony's age now)
-------
m = j-5 = 35 yrs (Matt's age now)
----
a = (1/2)j+5 = 25 yrs (Angie's age now)
