Answer:
47% of the students who chose pepperoni pizza as their favorite
Answer (D)
Step-by-step explanation:
∵ The total number of the students in grade 7 is
171 + 254 = 425 students
∵ The total number of the students in grade 8 is
285 + 143 = 428 students
∴ The total number of students in both grades is
425 + 428 = 853 students
∵ The number of students in grade 7 who like pepperoni pizza
as their favorite is 254
∵ The number of students in grade 8 who like pepperoni pizza
as their favorite is 143
∴ The number of students who like pepperoni pizza as their
favorite in both grades = 254 + 143 = 397 students
∴ % of student who chose pepperoni pizza as their favorite is
(397/853) × 100 = 46.5% ≅ 47%
∴ The answer is (D)
