Maya had $27. she spent all the money on buying 3 burgers for $x each and 2 sandwiches for $y each. if maya had bought 2 burgers and 1 sandwich, she would have been left with $11. a student concluded that the price of each burger is $5 and the price of each sandwich is $6. which statement best justifies whether the student's conclusion is correct or incorrect? (4 points) the student's conclusion is correct because the solution to the system of equations 3x + 2y = 11 and 2x + y = 16 is (5, 6). the student's conclusion is incorrect because the solution to the system of equations 3x − 2y = 11 and 2x − y = 16 is (5, 6). the student's conclusion is correct because the solution to the system of equations 3x + 2y = 27 and 2x + y = 16 is (5, 6). the student's conclusion is incorrect because the solution to the system of equations 2x + 3y = 27 and x + 2y = 16 is (5, 6).
