3. A technician worked 45 hours in one week He gets paid double for every hour over 40 hours that he works. If his regular wage is $825 per hour, approximately how much overtime pay should he receive plz explain

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

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.)
