In a certain year, the population of Smallburg was $4{,}000.$ In the following year, the population increased by $15\%.$ What was the resulting population?

4,600

Step-by-step explanation:

To solve this problem, we need to multiply add 15% of 4,000 back to 4,000.

First, change 15% into a decimal:

15% -> -> 0.15

Next, multiply 4,000 by 0.15:

The last step is to add the 600 back to 4,000:

The population of Smallburg the following year was 4,600.

the median is   36 orr sum like dat

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
