In a game a player gets 15 points for a correct answer and loses 10 points for an incorrect answer. The expression 15c - 10a represents the total for c correct and an incorrect answers. How many points are scored for 24 correct and 11 incorrect answers?
To find the total points scored for 24 correct and 11 incorrect answers, we substitute c = 24 and a = 11 into the expression 15c - 10a.
15c - 10a = 15(24) - 10(11)
= 360 - 110
= <<250=250>>250
Thus, 250 points are scored for 24 correct and 11 incorrect answers. Answer: \boxed{250}.
