Question

A computer system originally cost $1258.00. On Sunday it will be put on clearance. The clearance price will be $850. What is the percent of decrease rounded to the nearest percent?

Answer 1

You could use proportions for this.

1258.....1258-850

____  == ____

100%..... x%

1258x = 408(100)

1258x = 40800

x = 32%

Answer 2

around 32-33 percent off.

1258 x .325= 408.85

1258-580=408

Answer 3

The original cost is $1258.00

The clearance price is $850

Therefore the decrease in price is 1258 - 850 = 408

Thus, the percent of decrease = 408/1258* 100%

                                            = 32.342

                                            = 32 % (to the nearest percent)
