PLEASE HELP ME. The cost of building an airplane with 200 seats is about $100 million. If the cost, in millions of dollars, c , is proportional to the number of seats, s , what equation can be used to determine the cost, in millions of dollars, to build an airplane with any number of seats?

Drag one number to correctly complete the equation. Can someone please help with this

Respuesta :

S and C are proportional.
Therefore,
S/C=200/100=2
S/C=2
S/2=C is the answer.
