almond37 [142]

Answer:

We conclude that the percent of decrease = 20%

Step-by-step explanation:

Given

  • Original amount = $3930
  • Amount of decrease = $3930 - $3144 = $786

Using the formula

Percent of decrease = ( amount of decrease / orignal amount × 100 ) %

                                   = ( 786 / 3930 × 100 ) %

                                    = ( 0.2 × 100 ) %

                                    = 20%

Therefore, we conclude that the percent of decrease = 20%
