the cafeteria manager took a poll of 150 students to find the most popular lunch. the circle graph below displays the data. how many more students chose spaghetti and pizza than corn dogs, tacos, and cheeseburgers as their favorite lunch? a. 24 students b. 87 students c. 58 students d. 16 students
Answer
Explanation:
Step1: Calculate number of students who chose spaghetti
Multiply total students by spaghetti percentage. So, $150\times0.28 = 42$ students chose spaghetti.
Step2: Calculate number of students who chose corn dogs, tacos and cheeseburgers
First, find the combined percentage of corn - dogs, tacos and cheeseburgers: $12%+12% + 18%=42%$. Then multiply total students by this percentage: $150\times0.42 = 63$ students.
Step3: Find the difference
Subtract the number of students who chose spaghetti from the number of students who chose corn - dogs, tacos and cheeseburgers. $63 - 42=21$ students.
