At their outlet store, SportZ has a supply of soccer balls. To make room for other equipment, the balls are being marked don to sell quickly. The retail price is $22.99, and the store has advertised a sale of 30% off.

1. What is the sale price for the balls?
2. Due to a special promotion given to a school nearby, an additional $5.00 discount is given for each ball purchased. What is the resulting markdown rate?
