Answer

Explanation:

Step1: Analyze the relationship between Cole's and Tina's age

Cole's age is 3 years less than Tina's age (t). So Cole's age (=t - 3). Given Cole is 18, the equation is (t-3 = 18).

Step2: Solve the equation for (t)

Add 3 to both sides of the equation (t-3 = 18). (t-3+3=18 + 3) (t=21)

Answer:

A. The equation that represents this situation is (t - 3=18). Tina is 21.
