Stacey's average score on three maths tests is 84 Her last two test scores were 79 and 93 What was her first test score?
To find Stacey's first test score, we can use the formula for average: (sum of all scores) / (total number of scores). Stacey's total score on three tests is 84 x 3 = 252. Her last two test scores total 79 + 93 = 172. To find her first test score, we subtract the total of the last two tests from the total score: 252 - 172 = 80. Therefore, Stacey's first test score was 80.
What if your test grades are 83 94 86 and 91 what grade fo you need to earn on your next test to have an average of 90?
An average is worked out by dividing the total of the scores by the number of scores. You have 4 scores already so when you have done the next test it will be 5 scores. If you multiply 5 scores by 90 it gives you a total score of 450. The 4 scores you already have adds up to a total of 354. If you subtract 354 from the 450 you get 96 and that is your target for the final test. The average for the first 4 tests comes out at 88.5
