You are taking a science course in which there will be four tests, each worth 100 points. You have scores of 94,100, and 92 on the first three tests. You must make a total of 360 in order to get an A. What scores on the last test will give you an A?
The solution is {s|s>__}
(Simplify your answer. Type an integer or a decimal.)
You have 286 points now.
360-286 = ?
To find out what scores you need on the last test, you can use the formula:
Total score = (Score on Test 1) + (Score on Test 2) + (Score on Test 3) + (Score on Test 4)
In this case, the total score you need for an A is 360.
Let's substitute the values we know into the formula:
360 = 94 + 100 + 92 + (Score on Test 4)
Now, rearrange the formula to solve for the score on Test 4:
Score on Test 4 = 360 - (94 + 100 + 92)
Score on Test 4 = 360 - 286
Score on Test 4 = 74
Therefore, you will need to score at least 74 points on the last test in order to get an A in the course.
