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

Answer:

87.5%

Step-by-step 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 = $\frac{T_{2}-T_{1}}{T_{1}}\times 100=\frac{7}{8}\times 100=87.5$

Therefore, percent decrease in tickets written is 87.5 %.
