Jong earnee $100, and saved $30. what decimal part did he save

Hi, this question is a little unclear.  If you want to know what percentage he saved, it would be 30%, and to convert that percentage into a decimal would be a decimal of 0.30

$70.00

Step-by-step explanation:

Add .00 to the end of each amount.

Make sure that the decimal points are lined up like a straight line.

Subtract 100.00 - 30.00

You should receive 70.00 and don't forget the dollar sign at the end so the answer is $70.00.
