Answer:
The percent decrease of the population of certain city in 50 years is 13.97%
Step-by-step explanation:
You need to find the difference between the two numbers
5769-4963= 806
Then divide the decrease (806) by the original number
806/5769= 0,1397
And multiply the result (0,1397) by 100
0,1397 x 100 = 13.97%
