To solve the equation \( 100 + 27w = 343 \), we can follow these steps:

  1. Subtract 100 from both sides of the equation:

\[ 27w = 343 - 100 \] \[ 27w = 243 \]

  1. Now, divide both sides by 27 to solve for \( w \):

\[ w = \frac{243}{27} \] \[ w = 9 \]

Thus, it will take Destiny 9 weeks for her account to reach $343.

The correct response is 9 weeks.
