Defining the Quantities: The Golden Nut specialty store has obtained 60 lbs. of cashews
and 50 lbs. of premium almonds at a good price from its supplier. Since the almonds are
more expensive and more of a delicacy than the cashews, it is better to sell the cashews
mixed with almonds in order to get a better price for them. The storeowner decides to
sell two products: Hearty Nut Mix and Premium Blend.
1. If each pound of Hearty Nut Mix contains 4 ounces of almonds and 12 ounces of
cashews, write an expression that represents the number of pounds of each nut in x
pounds of the mix. [Hint: What fraction of the pound is cashews, and what fraction is
almonds?]
2. If each pound of Premium Blend contains 8 ounces of almonds and 8 ounces of
cashews, write an expression that represents the number of pounds of each nut in y
pounds of the mix.
3. Complete the following table and use it to write an expression that represents the
total number of pounds of cashews used for both mixes together. Then, write an
expression for the total number of almonds used for both mixes together.

4. Finally, your market research shows that since the Premium Blend is much more
popular, you can afford to charge quite a bit more for it, obtaining a profit of $0.45 per
pound for it while you can only earn a profit of $0.30 per pound for the Hearty Nut
Mix. Write an expression for the amount of profit that you would make from selling x
pounds of Hearty Nut Mix and y pounds of Premium Blend.
