Answer:

Option A is correct answer.

Step-by-step explanation:

Here age of Tina is given to be t

Cole's age = 3 year less than Tina's age ,that is t-3

which is given to be 18

therefore equating both we get

t-3=18

adding 3 both sides in order to solve for t ,we get

t = 18+3

t= 21 years

therefore Equation to find the age of Tina is t-3 =18 and

the age of Tina is 21 years.

Therefore option A is correct answer.
