Question

Officer Brimberry wrote 8 tickets for traffic violations last week, but only 1 ticket this week. What is the percent decrease? Give your answer to the nearest tenth of a percent.

Answer 1

87.5%

Explanation:

Given:

Number of tickets written in the last week,
`T_(1)=8`

Number of tickets written in this month,
`T_(2) =1`

Difference in tickets written =
`T_(2)-T_(1)=8-1=7`

∴ Percent decrease =
`(T_(2)-T_(1))/(T_(1))* 100=(7)/(8)* 100=87.5`

Therefore, percent decrease in tickets written is 87.5 %.
