Maria is saving money for a new bicycle. She already has $25 and plans to save an additional $10 each week. Let's define a linear function, $$f(w)$$, where $$w$$ represents the number of weeks she saves money, and $$f(w)$$ represents the total amount of money she has saved after $$w$$ weeks.

What is the total amount of money she will have after 3 weeks? Please enter your answer in the grid below.
