Answer: [tex]\frac{22}{25}c[/tex]
0.88c
Step-by-step explanation:
The former crime rate was [tex]c[/tex] incident per 1000 people.
Decrease in the crime rate = 12%
That is ,we will find 12% of [tex]c[/tex] and then subtract from the original crime rate which is
12% of c = 0.12c
Therefore: the new crime rate will be :
[tex]c - 0.12c[/tex]
that is :
[tex]c - \frac{12}{100}c[/tex]
which will be:
[tex]\frac{88c}{100}[/tex]
which is :
[tex]\frac{22}{25}c[/tex]
which is the same as 0.88c
