To find out how many weeks it will take Charlie to save $220, we first need to determine how much more money he needs to save.
He currently has $85.45 and wants to reach $220:
\[
\text{Amount needed} = 220 - 85.45 = 134.55
\]
Charlie's savings rate is $24.50 per week. To find out how many weeks it will take to save $134.55, we divide the amount needed by the amount he saves each week:
\[
\text{Number of weeks} = \frac{134.55}{24.50} \approx 5.49
\]
Now, we will round this to the nearest tenth:
\[
5.49 \approx 5.5
\]
Thus, it will take Charlie approximately \( \mathbf{5.5} \) weeks to save $220.
The correct answer is **5.5 weeks.**
