Example: To divide 0.3 / 4, look at the numerator and look at the denominator and ask "How many digits are AFTER the decimal point?" In this fraction, you would say "1" and "0", respectively.
Make those two numbers (1 and 0) equal by changing the denominator from 4 to 4.0. Now, you have 0.3 / 4.0. Throw away the decimal points for the fraction 3 / 40. Then just divide.

He save $43.58
His final bill would be $80.92
Solution #1:
35/100 × $124.50 = $43.575
When you round $43.575 to the nearest hundredths you will get $43.58
Solution #2:
$124.50 - $43.58 = $80.92
