Given the statement:
Cole's age is 3 years less than his sister Tina's age, t.
Determine the equation that represents the age of Tina if Coe is 18.
Solution:
In order to determine the age of Tina, we simply subtract 18 by 3, since it is stated that Tina's age is 3 years less than Cole. We can represent the given equation as,
Age of Tina = Age of Cole - 3
Age of Tina = 18 - 3
Age of Tina = 15
Final answer:
Tina is 15 years old.
