Jason had $32. he spent all the money on buying 4 cds for $x each and 2 magazines for $y each. if jason would have bought 5 cds and 2 magazines, he would have run short of $4.
a student concluded that the price of each cd is $5 and the price of each magazine is $6. which statement best justifies whether the student's conclusion is correct or incorrect? a. the student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 4 and 5x + 2y = 36 is (9, 4).
b. the student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).
c. the student's conclusion is correct because the solution to the system of equations 4x + 2y = 4 and 5x + 2y = 36 is (5, 6).
d. the student's conclusion is correct because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (5, 6).
