If Anne is 8, Teresa is 24. In 7 years Anne will be 15, and Teresa will be 31 ☺☺☺☺

Teresa is three times older than her sister Anne. If Anne is 8 years old now, how old is Teresa when Anne is 15 years old.
--------
1 time older = 2x as old
2 times older = 3x as old
3 times older = 4x as old
---
A = 8
T = 32
============
15 - 8 = 7
32 + 7 = 39
===========================
