The population of cats in a town increased by 25% from Year 1 to Year 2. The population of cats in Year 2 is 60.

See explanation

Step-by-step explanation:

Your question isn't complete but I guess that you want to find the population of the cats in Year 1. This will be represented by x. Therefore,

x + (25% × x) = 60

x + (0.25 × x) = 60

x + 0.25x = 60

1.25x = 60

x = 60/1.25

x = 48

The population of cats in year 1 is 48

the discriminant is 64 + 4*1*12 = 112

this is prime.
