Answer 1

1940.3

Explanation:

The current population value is 13,400

Let the previous population be represented by y

The population of the city decreased by 33

Therefore the previous population can be calculated as follows

13400= y(100-33)/100

13400=( y×67)/100

13400= 100× 13400/67

= 100× 19.402

= 1,940.3

Hence the previous population is 1,940.3
