The survey is of 18 students, but in reality there are 90 students in total, so what we will do is an approximate to know the number of types of food in total:

Hamburgers:


10\cdot(90)/(18)=\text{ }50

therefore 50 hamburgers were ordered

Hot dogs:


7\cdot(90)/(18)=35

therefore 35 hot dogs were ordered

Veggie burger:


\begin{gathered} 1\cdot(90)/(18)\text{ = 5} \\ \end{gathered}

therefore 5 veggie burger were ordered
