Given : Dalam ulangan matematika setiap jawaban benar diberi nilai 4,salah nilai -2 dan tidak jawab -1. Dari soal 40 kalian menjawab benar 30, salah 6 dan tidak jawab 4.
To find : Berapa nilai kalin
Solution:
In math tests each correct answer is given a value of 4, wrong value -2 and no answer to -1. From question 40 you answered correctly 30, wrong 6 and no answer 4.
30 * 4 = 120
6 *( - 2) = -12
4 * (-1) = - 4
120 - 12 - 4
= 120 - 16
= 104
Score = 104
