Question 831075
Let B = Moochelle's age
Let F = Fiona's age
Let M = Madeline's age
.
Here's the information from the question:
B = 3F (Michelle is three times as old as Fiona)
F = 2M (Fiona is twice as old as Madeline)
M = 7 (Madeline is seven years old)
.
If F is 2M, then F = 2*7 = 14
Since B is 3F, and we know F to be 14, multiply 3*14 to get
42 <<--
