Given the statement:
Officer Brimberry wrote 32 tickets for traffic violations last week, but only 4 tickets this week.
Determine the percent of decrease.
Solution:
In order to detemrine the percent of decrease we subtract 32 with 4, then divide the difference by 32.
= 32 - 4
= 28
= 28/32
= 0.875
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.875)(100)
= 87.5%
Final answer:
The percent of decrease is 87.5%.
