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?

Answer 1

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.
