eric scored 66% on his most recent maths test. he has studied hard and is determined to improve his score on the next topic test. which will be out of 32 marks. what is the least number of marks eric can score to improve on his previous score
x/32 > 66/100
x > 32*66/100
x > 21.12 , let's assume all scores are whole numbers.
He must get a score of at least 22
m / 32 > .66
round the result up to the next whole number
To determine the least number of marks Eric can score to improve on his previous score, we first need to calculate his current score out of 32 marks.
Eric scored 66% on his most recent maths test, which means he obtained 66% of the total marks.
Let's calculate his current score out of 32 marks:
Current Score = (Percentage Scored / 100) * Total Marks
Current Score = (66 / 100) * 32
Current Score = 0.66 * 32
Current Score = 21.12 marks
Since the current score cannot be a decimal, Eric cannot score 21.12 marks. He needs to score at least 22 marks to improve on his previous score.
To find the least number of marks Eric can score to improve on his previous score, we need to determine the minimum score he needs to achieve.
Given that Eric scored 66% on his most recent math test, we can calculate his score by multiplying his percentage by the total marks. Let's assume the total marks on his most recent test were out of 100.
Eric's score = 66% of 100 = (66/100) * 100 = 66 marks
Now, to improve his score, he needs to score higher than 66 marks on the next test, which is out of 32 marks.
Therefore, the least number of marks Eric needs to score to improve on his previous score is 67 marks or more out of 32.
