Will mark brainliest harry had $32. he spent all the money on buying 3 notebooks for $x each and 4 packs of index cards for $y each. if harry had bought 5 notebooks and 5 packs of index cards, he would have run short of $18. a student concluded that the price of each notebook is $5 and the price of each pack of index cards is $1. which statement best justifies whether the student's conclusion is correct or incorrect? the student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2). the student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (8, 2). the student's conclusion is correct because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (5, 1). the student's conclusion is correct because the solution to the system of equations 3x − 4y = 32 and 5x − 5y = 50 is (5, 1).
