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? 1) the student's conclusion is correct because the solution to the system of equations 3x + 2y = 11 and 2x + y = 16 is (5, 6). 2) the student's conclusion is incorrect because the solution to the system of equations 3x − 2y = 11 and 2x − y = 16 is (5, 6). 3) the student's conclusion is correct because the solution to the system of equations 3x + 2y = 27 and 2x + y = 16 is (5, 6). 4) the student's conclusion is incorrect because the solution to the system of equations 2x + 3y = 27 and x + 2y = 16 is (5, 6).

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
