In order to figure out what N is you have to isolate it by dividing by 50 on both sides as shown below:
$N*50=5000\\\frac{n*50}{50}=\frac{5000}{50}\\n=100$

The rabbit population in a certain area is 500% of last year's population. There are 700 rabbits this year. How many were the

Ksenya-84 [330]

For this case we have the following data:

700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:

700 -----------> 500%

x ---------------> 100%

Where x represents the rabbit population of last year.

Clearing x we have:

$x = \frac{ 100 * 700}{500}$

$x = 140$ rabbits

In this way, last year there was a population of 140 rabbits.

Answer:

140 rabbits
