After batman brought the joker to justice , the crime rate in arkham city decreased by 12%. Previously the crime rate was c inci
alexandr402 [8]

Previous crime rate = c incidents per 1,000 people

Reduction in crime rate after batman brought the joker to justice = 12%

Hence, new crime rate (per 1,000 people) would be = c - 12%×c

⇒ New crime rate (per 1,000 people) would be = c - 0.12×c

⇒ New crime rate (per 1,000 people) would be = 0.88×c

Hence, now the crime rate is 0.88×c per 1,000 people.
