Me! i don't really understand this so if you can explain it would make the concept of this easier for me

If you wanted to find 99% of 180 you'd multiply 180 by .99

If you wanted to find 1% of 180 you'd multiply 180 by .01.

Because the problem asks for a ten percent increase we need to find what 10% of 180 is and then because it increases we add this number to 180 to get our answer.



so 10% of 180 is 18.
