Dan and Mario went to a sandwich shop to buy sandwiches for their group of friends. Dan bought 2 tuna and 5 vegetarian sandwiches for $37. Mario bought 4 tuna and 3 vegetarian sandwiches for $39. Which system of equations can be used to solve for the cost of each kind of sandwich? 2 x + 5 y = 37. 4 x + 3 y = 39.
2 x + 5 y = 39. 4 x + 3 y = 37.
5 x + 2 y = 39. 4 x + 3 y = 37.
5 x + 2 y = 37. 4 x + 3 y = 39.
