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.

How many students ordered hot dogs? ** If the 30 students who ordered burgers were twice the number of students who ordered hot dogs, then 30/2 = <<30/2=15>>15 students ordered hot dogs.
How many students were at the restaurant? ** The total number of students is 15 + 30 = <<15+30=45>>45
