--------------------------------------
Quantity::: mms + it = 19
Value::::::100mms + 120it = 2000
-------------------------------------
Multiply thru the 1st equation by 100 to get:
100mms + 100it = 100*19
100mms + 120it = 2000
---------------------------
Subtract and solve for it:
20it = 100
it = 5 (# of itune songs downloaded)
-----
Solve for mms:
mms + it = 19
mms + 5 = 19
mms = 14 (# of mm songs downloaded)
