Question

Justin is 2 years older than one third Marcella’s age. Aimee is four years younger than 2 Times Justin’s age. Define a variable and write an expression to represent Justin’s age. Then find Justin’s age and Aimee’s age if Marcella is 63 years old.

Answer 1

j = (1/3)m + 2, and
a = 2j - 4

If Marcella (m) is 63, then Justin is (1/3)(63) + 2, or 23. (23 years old)

Aimee (a) is 2(23) - 4 years old, or 46-4, or 42 years old.
