I believe it's 3 months because 12 divided by 4 is 3.
Answer:
Susanne is 16
Step-by-step explanation:
Let x be Dakota's age
x + 3 = Susanne's age
4(x+3) = Bob's age
Sum of their age is:
x + x + 3 + 4(x + 3) =
Simplify:
x + x + 3 + 4x + 12
6x + 15 = 93
6x = 78
x = 13
Susanne is 3 more than x (13 +3) which is 16
