To work out how much it is for a pound of pistachio or almonds:
You subtract 8 from 48 which leaves you with 40 then you divide 40 with 5 which leaves you with 8 (meaning $8 for a pound for almonds) and you add 4 to 8 which gives you 12 ($12 for a pound of pistachios)
then you substitute the answers into a, b, c,d and e.
