You can put this solution on YOUR website! Carrie is three times older than Julio. If the sum of their ages is 48, how old is Julio
----------------
J = Julio's age
C = Carrie's age
===================
C = J + 3J = 4J
J + 4J = 48
J = 9.6
C = 28.8
==============================
1 time older = 2x as old
2 times older = 3x as old
etc.
======================================
People who don't know what they're doing should not try to write math books.
