lucy's birth year + mother's birth year + lucy's age + mother's age

Since their birthdays occurred in January, and it is now March...

lucy's age = 2015 - lucy's birth year

mother's age = 2015 - mother's birth year

Substitute these values in for lucy's age and mother's age.

= lucy's birth year + mother's birth year + (2015 - lucy's birth year) + (2015 - mother's birth year)

= lucy's birth year + mother's birth year + 2015 - lucy's birth year + 2015 - mother's birth year

= 2015 + 2015

= 4030
