Question

Pet food inc. created a new packet size that was 25% larger than the old package if the old package contained 20 pounds how much does the new package contain?

Answer 1

the new package weighs 25 pounds
do you need and explanation?

Answer 2

Well you put the decimal two times to the right 20%  (the percent is where the decimal starts) .20

Then multiply that by the original amount which gives you 4. 

Add 20 and 4.

= 24 pounds

That's my best guess, hope i'm right
