Question

Officer Brimberry wrote 8 tickets for traffic violations last week, but only 5 tickets this week. What is the percent decrease? Give your answer to the nearest tenth of a percent.

Answer 1

(Last weeks value-this weeks value)/(Last weeks value)
(8-5)/(8)
3/8=0.375
*100 to get percentage
0.375*100=37.5% decrease

Answer 2

The percent decrease is
`37.5\%`

Explanation:

we know that

`8\ tickets` ------> represent the
`100\%`

so

by proportion

Find the percent decrease

`(100)/(8)(\%)/(tickets) =(x)/((8-5))(\%)/(tickets) \\ \\x=100*(8-5)/8\\ \\x=100*3/8\\ \\x=37.5\%`
