Tanya is 1 year less than three times the age of her sister Jessica. Jessica is five years old. How old is Tanya? Need an equation
T = 3J -1
To find Tanya's age, let's first assign variables to the information given in the question.
Let's say:
T = Tanya's age
J = Jessica's age
It is given that Jessica is five years old, so J = 5.
According to the question, Tanya is one year less than three times Jessica's age. Mathematically, this can be represented as:
T = 3J - 1
Substituting the value of J into the equation, we have:
T = 3(5) - 1
Simplifying further:
T = 15 - 1
T = 14
Therefore, Tanya is 14 years old.
