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? (4 points)
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 correct because the solution to the system of equations 3x + 4y = 32 and 5x + 5y + 18 is (5, 1).
The student's conclusion
correct because the solution to the system of equations 3x – 4y = 32 and 5x - 5y = 50 is (5, 1).
