(2) The price of for the magazine is \$5.

Let the number of books purchased = a and the magazines purchased = b
Hence you can write the equations ------- ax +by = 50 + 100 = 150

S1. Tells you that a = 10
S2. y = 5

Now we have three equations but four unknowns

IMO E

too many variables and too less equation => not solvable
IMO E
