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?

Question

1. 250
2. 360
3. 470
4. 110

Answer 1

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.
