Kevin spend a total of $50.43 on sandwiches and water for his friends, and he purchases two more sandwiches than bottles of water. Create a system of equations to model the situation above, and use it to determine if the solution of the system is viable.

A) there is not enough information to determine whether the solution of the system is viable.

B) Kevin purchases seven sandwiches and five bottles of water; therefore the solution is viable for the given situation.

C) Kevin cannot purchase a negative number of sandwiches or a negative number of bottles of water; therefore the solution is not viable for the given situation.

D) Kevin cannot purchase a negative number of bottles of water; therefore the solution is not viable for the given situation.
