Question
Consider the linear function ƒ(x) 25x + 250 for the following context. Wanda starts off with $250 in her bank account. If she saves $25 every week (where x represents the number of weeks that she has been saving money), how much would Wanda have in her account after 17 weeks?

To find out how much Wanda would have in her bank account after 17 weeks, we can use the function \( f(x) = 25x + 250 \), where \( x \) represents the number of weeks.
Substituting \( x = 17 \) into the function:
\[
f(17) = 25(17) + 250
\]
Calculating \( 25(17) \):
\[
25 \times 17 = 425
\]
Now, add this to 250:
\[
f(17) = 425 + 250 = 675
\]
Therefore, after 17 weeks, Wanda would have **$675** in her bank account.
