Answer 1

Ian's percent of decrease based on the cost of the computer is 78.75%. It is calculated by dividing the decrease by the original price and then multiply it by 100. The decrease is $1200 minus $255, which equals to $945. $945 divided by $1200 is 0.7875. Multiply that by 100 and you have 78.75%.
