Previous crime rate = c/1000

Decrease in crime rate after Batman brought joker to justice = 12%

New crime rate = (c/1000) - (12/100) × (c/1000)

= (100c - 12c) ÷ 100000

= 88c ÷ 100000

= 0.00088c

0.88c  per 1000 people & 22c/25 per 1000 people are two correct answers

Step-by-step explanation:

Previously, the crime rate was c incidents per 1 0 0 0 people

Crime rate  = c  per 1000

the crime rate in Arkham City decreased by 1 2 %

Decreased crime rate = c - (12/100)c  = 0.88c  per 1000 people

0.88c  = 88c/100  = 22c/25 per 1000 people
