Sagot :

5 percent of 2700 is 135 so the answer is $2700

$2700

I know $135 is 5%, so $270 is 10% (because 5% + 5% = 10%). If you know what 10% of an amount is, you can just multiply that number by 10 to get to 100%. 270x10=2700

Another way to do this would be to say an unknown number, x, times 5% (0.05) equals $135. That equation would be 0.05x=135. Divide each side by 0.05 to get x = 2700

I hope this helps!
