Question 328019: Need help solving:
A student took a test composed of 20 questions, with correct answers worth 3 points. If the student received 48 points for his grade, how many questions were correct? Answer by meay7c(10) (Show Source):
You can put this solution on YOUR website! Here we have a test with 20 questions. With each question being worth 3 points.
Let's multiply the number of questions by the point value to determine the total number of points possible for the test:
20 * 3 = 60.
So the test is worth 60 points.
The student scored 48 points out of 60 points. Next we determine the percentage the student answered correct:
48 / 60 = .80
The student scored 80% or .80 on his / her test. Now we take this .80 to determine the actual amount of problems the student got correct.
There were 20 questions, so the student got 80% of the 20 questions correct. We use multiplication as the word "of" denotes multiplication:
.80 of 20 = .80 * 20 = 16 questions answered correctly.
You can check your answer also:
16 questions answered correctly * 3 points = 48 Yes!!!
Good Luck :-)
