Given the statement:
Omar scored an 82% on his first test of the quarter.
Determine whether a score of 38 out of 50 on the second test will help or hurt his grade.
Explanation:
Let us assume that the passing mark for his grades is 75%, thus we already have the first mark which is 82%. To find for the second mark, we simply divide 38 by 50.
= 38/50
= 0.76
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.76)(100)
= 76%
Now we need to take the average of the two quizzes by adding the percentage and dividing by 2.
= ((82%) + (76%))/2
= 158%/2
= 79%
Final answer:
The score will help his grade maintain an average above 75%.
