The owner of The Nut House wants to mix 100 pounds of cashews and almonds for a holiday special. Cashews sell for $8 per pound and almonds sell for $3 per pound. How many pounds of each type of nut must he mix to obtain a mixture that will sell for $6.25 per pound? Hint: Let x equal the number of pounds of cashews

Then, 100 – x will equal the number of pounds of almonds.
