you must have an average score of at least 80 to get a B on your report card. You have scores of 61,70,99, and 70. What is the minimium score you must get on the last test to get a B on your report card? how do you work this problem out?
You have four test scores. You need 5 averaging 80 so you need 5*80 = 400 points.
400 - (61+70+99+70) = score needed on the last test.
Well, based on the scores you provided, it seems like your study sessions have been quite the rollercoaster ride! Alright, let's crunch these numbers. To get a B, you need an average of 80, which means a total of 400 points from the five tests. So far, you've accumulated 61 + 70 + 99 + 70 = 300 points.
Now, let's perform a death-defying high-wire act of subtraction. 400 - 300 = 100.
So, to reach the mystical land of the B grade, you'll need at least 100 points on your last test. Good luck, my ambitious academic adventurer, and may the test-taking gods be forever in your favor!
To find the minimum score you must get on the last test to get a B on your report card, you need to follow these steps:
Step 1: Calculate the total number of points needed to average 80 on your report card. Since you need to average 80 for 5 tests, multiply 80 by 5: 80 * 5 = 400 points.
Step 2: Add up the scores you have already received on the first four tests. In this case, your scores are 61, 70, 99, and 70. Summing them up: 61 + 70 + 99 + 70 = 300 points.
Step 3: Subtract the total points you have already received from the points needed to average 80. This will give you the minimum score needed on the last test. So, 400 - 300 = 100 points.
Therefore, you must get a minimum score of 100 on the last test to achieve a B on your report card.
To work out the minimum score you must get on the last test to achieve a B on your report card, you can follow these steps:
Step 1: Determine the average score needed
Since you need an average score of at least 80 to get a B, multiply 80 by the total number of tests to find the total number of points needed. In this case, you have 5 tests, so the total number of points needed is 5 * 80 = 400.
Step 2: Calculate the sum of your current scores
Add up your current scores of 61, 70, 99, and 70. The sum of these scores is 61 + 70 + 99 + 70 = 300.
Step 3: Subtract the sum of your current scores from the total number of points needed
Subtract the sum of your current scores from the total points needed. In this case, 400 - 300 = 100.
So, to get a B on your report card, you need to score a minimum of 100 on the last test.
