n 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 a incorrect answers. How many points are scored for 24 correct and 11 incorrect answers?
1. 250
2. 360
3. 470
4. 110
To find the total points for 24 correct and 11 incorrect answers, substitute c=24 and a=11 into the expression 15c−10a.
Total points = 15(24) - 10(11)
= 360 - 110
= 250
Therefore, the correct answer is 1. 250.
