With percentages, you just need to move the decimal point over 2 places to the left. Therefore, 30% = 0.30
Whenever you see the word "of" in a math problem, you can usually replace it with "multiplied by". Meaning: "What is 0.30 multiplied by 90 dollars?"
0.30 x $90 = $27

think about it this way...
What's 10% of $90? $9
If $9 is 10% of $90 then, 30% of $90 is $9+$9+$9=$27
$27

Is that all you have left from the $90 your grandma gave you last week? 30%? And so you're going to tell her your dog at the rest? Do yourself a favor and tell her the truth when she asks, because I think she was testing your frugleness when she gave it to you in the first place, and it's not going to look good if you can't make good consumer sense out of how you applied it.
Just trying to help.....Even when no one asks.
