4 percent of change i have

joqual

32 minutes is going to be 100% . Then 28 is going to be something % 10% of 32=3.2 Just move the decimal to the left once. 20%=6.4 30%=9.6 40%=12.8 50%=16.0 60%=19.2 70%=22.4 80%=25.6 90%=28.8 Just keep adding 3.2 . 28 is between 80% and 90% . 81%=25.92 Now we are adding one percent not 10 . One percent is .32 , just move the decimal to the left again. 82%=26.24 83%=26.56 84%=26.88 85%=27.2 86%=27.52 87%=27.84 88%=28.16 It would basically be 87 percent point something. 87 - 100 = 13 The percent decrease is 13 13%
