Question

Ned took a test with 28 questions. He lost 3 points for each of the 7 questions he got wrong and earned an additional 10 points for answering a bonus question correctly. How many points did Ned receive or lose overall?.

Answer 1

Points received 17 and lost 11 overall

Explanation:

• To find the points Ned received, we subtract the points lost for incorrect answers from the total possible points and then add the points earned for the bonus question:

Points Received = Total Possible Points - Points Lost + Points Earned

Points Received = 28 - 21 + 10

Points Received = 7 + 10

Points Received = 17

Ned received a total of 17 points on the test.

• To find the overall points Ned lost, we subtract the points earned for the bonus question from the points lost for incorrect answers:

Overall Points Lost = Points Lost for Incorrect Answers - Points Earned

Overall Points Lost = 21 - 10

Overall Points Lost = 11

Ned lost a total of 11 points overall on the test.

I hope that helps
