A department store offers two promotions for shoe purchases. Promotion A says, "Buy one pair of shoes, get the second pair for half the price." Promotion B now varies based on cost: "Get a $15$ discount on the second pair if its original price is $30$ or above, or get a $5$ discount if the price is below $30."
