Final answer:
The equation to solve the problem is 64 = 4(a - 44), which results in Sarah's age being 60 years old.
Step-by-step explanation:
To solve the problem, we can write an equation using the information given:
64 = 4(a - 44)
Where 'a' represents Sarah's age.
We can solve this equation by dividing both sides by 4:
16 = a - 44
Next, we can isolate 'a' by adding 44 to both sides:
a = 16 + 44
a = 60
Therefore, Sarah's age is 60 years old.
