Hi there!
Your answer is A, S=4A. S is representing Sam's age and the 4 is representing how many times older Sam is than Allie. Allie is represented by the variable A.
Notice I said "4 is representing how many times older Sam is than Allie."
A variable next to a number means to multiply, and times =multiply. Isn't the 4 next to the A?
Hope this helps!
