0.375 i think is the answer

Answer with explanation:

Number of tickets wrote by Officer Brimberry last week = 32

Number of tickets wrote by Officer Brimberry this week = 20

Percent Decrease

     [tex]=\frac{\text{Last week}-\text{This week}}{\text{Last week}}\times 100\\\\=\frac{32-20}{32}\times 100\\\\=\frac{12}{32}\times 100\\\\=\frac{1200}{32}\\\\= 37.5[/tex]
