In a 50-question test, the highest score in the class is three times the lowest score minus four. The difference between the highest score and the lowest score is 30. What is the lowest score? A) 27 B) 17 C) 15 D) 14

B) 17

Step-by-step explanation:

The highest score is three times the lowest score minus 4, so:

17 (lowest score) x 3 = 51

51-4 = 47 (highest score)

The difference between the highest score and the lowest score is 30:

47 - 17 = 30

So 17 would have to be the lowest score
