Question 386766
Grant is five times as old as Francis. One third of the sum of their ages is equal to 32. Find their ages.
-----------------------------------
Equations:
g = 5f
(1/3)(g+f) = 32
---
Rearrange:
g=5f
g+f = 96
----
Substitute for "g" and and solve for "f":
5f + f = 96
6f = 96
f = 16 (Francis' age now)
---
Since g = 5f, g = 5*16 = 80 (Grant's age now)
