Sophie does 4 loads of laundry a week and uses 1 dryer sheet per load.  A box of dryer sheets costs $5.50 and has 104 dryer sheets in a box.  On her birthday, she was given wool dryer balls to use instead of dryer sheets.  How much money does she save in a year not buying dryer sheets?
She does 4 loads of laundry a week and used 1 dryer sheet per load for a total of 4*1 = <<4*1=4>>4 dryer sheets in a week
She used 4 dryer sheets per week for 52 weeks for a total of 4*52 = <<4*52=208>>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 = $<<5.50*2=11.00>>11.00 by not buying dryer sheets
