1. When you add the digits in multiples of 9, the answer is 9.

9, 18, 27, 36, 45, 54, 63, 72, 81, 90, (99), 108, 117, etc.

2. The price of cleaning the sport coat was raised 25%. To find how much cleaning a jacket costs now, multiply .25 by $10.

1/4 = .25 = 25%

25% of $4.00 = $1.00.

The cleaners raised the price $1.00 from $4.00 to $5.00.
