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)
