Problema Solution
Christopher is 27 years younger than Vanessa. For the last two years, Vanessa and Christopher have been friends. Six years ago, Vanessa was 44 times as old as Christopher. How old is Christopher now?
Answer provided by our tutors
let
c = the present age of Christopher
v = the present age of Vanessa
Christopher is 27 years younger than Vanessa:
c = v - 27
Six years ago, Vanessa was 44 times as old as Christopher:
v - 6 = 44(c - 6)
by solving the system of equations:
c = v - 27
v - 6 = 44(c - 6)
we find:
c = 6.6 years
v = 33.6 years
