Answer:

The answer rounded to the nearest whole number is 1729

Step-by-step explanation:

Set it up like this: Percent in fraction form = x over total

So: 34/100 = x/5086

You then multiply: 34 x 5086 = 172924

Then divided that number by 100: 172924 divided by 100 = 1729.24

Then round the number to the nearest whole number: 1729

Hope this helps good luck!
