The step-by-step working

Written out in full, the way it should appear on paper.

  1. 100% - 45% = 55%
  2. the money left after the fridge = 55% of the money at first
  3. 20% of 55% = 20/100 × 55% = 11%
  4. 55% - 11% = 44%
  5. 44% = $1540
  6. 1% = $1540 ÷ 44 = $35
  7. 100% = 100 × $35 = $3500

The answer is $3500.
