### Steps/Work

For john

Cost of Computer = $2000

Sales tax = (5/100)*2000 = $100

Total Cost of Computer = 2000 + 100 = 2100

For Henry

Cost of Computer = $1800

Sales tax = (12/100)*1800 = $216

Total Cost of Computer = 1800 + 216 = 2016

% that Henry paid less than john = (2100 - 2016)*100/2100 =4%

Answer: Option B

Cost of Computer = $2000

Sales tax = (5/100)*2000 = $100

Total Cost of Computer = 2000 + 100 = 2100

For Henry

Cost of Computer = $1800

Sales tax = (12/100)*1800 = $216

Total Cost of Computer = 1800 + 216 = 2016

% that Henry paid less than john = (2100 - 2016)*100/2100 =4%

Answer: Option B
