She does 4 loads of laundry a week and used 1 dryer sheet per load for a total of 4 * 1 = 4 dryer sheets in a week.

She used 4 dryer sheets per week for 52 weeks for a total of 4 * 52 = 208 dryer sheets.

Her box of dryer sheets has 104 sheets so she needs 208 / 104 = 2 boxes of dryer sheets.

Each box costs $5.

50 and she used 2 boxes so she now saves 5.

50 * 2 = $11.

00 by not buying dryer sheets.

The answer: 11
