64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44

Answer=Sarah is 60 years old

If 64 is 4 times the difference between sarah's age and 44, then '64/4' would be the difference between sarah's ages and 44.

difference=64/4=16

The difference between Sarah's age and 44 is 16.

So Sarah is either '44+16' years old, or '44-16' years old

a=44+16=60 years old

a=44-16=28 years old

Since the problem says Sarah is older than 44, she must be 60 years old
