Can someone please answer step by step? Jane wants to buy a jacket that costs $75 but that is on sale for 20% off. She also has a coupon for 10% off. She tells her friend George that she can calculate the discounted price of the jacket by finding 30% of $75. George disagrees and states that she first needs to find 20% of $75 and then find 10% of your answer. Who is correct and why?

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
