C) You correctly answered 15 out of 20 problems on your test. What is your percent score?
D) At the Liberty Tree Mall 1,300 people took the Coke/Pepsi challenge.55% of those challenged preferred Coke. How many people selected Coke?
C) To find the percent score, you can use the formula:
Percent score = (Number of problems answered correctly / Total number of problems) * 100
In this case, the number of problems answered correctly is 15, and the total number of problems is 20. Plugging these values into the formula, we get:
Percent score = (15 / 20) * 100
Percent score = 0.75 * 100
Percent score = 75%
Therefore, your percent score is 75%.
D) To find the number of people who selected Coke, you can use the following formula:
Number of people selecting Coke = (Percentage of people preferring Coke / 100) * Total number of people
In this case, the percentage of people preferring Coke is 55% and the total number of people who took the challenge is 1,300. Plugging these values into the formula, we get:
Number of people selecting Coke = (55 / 100) * 1,300
Number of people selecting Coke = 0.55 * 1,300
Number of people selecting Coke = 715
Therefore, 715 people selected Coke.
C) To calculate the percent score, you need to divide the number of problems answered correctly by the total number of problems, and then multiply by 100. In this case, you correctly answered 15 out of 20 problems. So, you would calculate it as follows:
Percent Score = (Number of Correct Answers / Total Number of Problems) * 100
Percent Score = (15 / 20) * 100
Percent Score = 0.75 * 100
Percent Score = 75%
Therefore, your percent score is 75%.
D) To find out how many people selected Coke, you need to multiply the total number of people who took the Coke/Pepsi challenge by the percentage of those who preferred Coke. In this case, 55% of the 1,300 people preferred Coke.
Number of People who selected Coke = (Percent who preferred Coke / 100) * Total Number of People
Number of People who selected Coke = (55 / 100) * 1300
Number of People who selected Coke = 0.55 * 1300
Number of People who selected Coke = 715
Therefore, 715 people selected Coke.
