asked • 11/18/17In a certain archery competition, archers shoot 25 arrows and receive penalty points for each missed shot: 1 penalty point for the first miss and for each subsequent miss a penalty that is ½ point greater than for the previous miss. If an archer received 7 penalty points total, how many times did he hit the target?
