To find the equation representing the relationship between Lisa's age and Sammy's age, let's analyze the information given:
1. Lisa's age is 4 years older than three times Sammy's age.
2. Lisa's current age is 28 years old.
We can express this relationship with the following equation:
Lisa's age = 3 * Sammy's age + 4
In terms of the variable \( s \) (which represents Sammy's age), we can write:
28 = 3s + 4
This equation can be rearranged to:
3s + 4 = 28
So the correct response is:
**3s + 4 = 28**
