:
When Dad died Carrie was 10 and Dad was 52, using this point of reference:
Let a = no. of yrs when C will 1%2F3 Dad's projected age
:
10 + a = 1%2F3(52+a)
multiply both sides by 3
3(10+a) = 52 + a
30 + 3a = 52 + a
3a - a = 52 - 30
2a = 22
a = 11 yrs for this to be true
then
10 + 11 = 21 yrs old when Carrie is rich
