Question

Micaela is 2 years older than Sam. In 4 years, the sum of their ages will be 40. How old is Micaela now?

Answer 1

Let Micaela be M
Let Sam be S

M = 2 + S

In 4 years, their ages will be 40 in all

Subtract 8 (because it is 2 people) from 40

40 - 8 = 32

then use 32 to find their ages.


M = 2 + S
S

32 - 2 = 30

30/2 = 15

Sam is 15
Micaela is 15 + 2, or 17

Sam is 15, Micaela is 17

hope this helps
