After a trip, Mrs. Nalani took the students to the restaurant and told them they could order either a burger or a hot dog. If the number of students who ordered burgers was 30, twice the number of students who called for a hot dog, calculate the number of students at the restaurant. Give me reasons, before answering the question
If the 30 students who ordered burgers were twice the number of students who ordered hot dogs, then 30 / 2 = 15 students ordered hot dogs. The total number of students is 15 + 30 = 45. So the final answer is 45.
