Find the price of each nut.

The almonds were 3 dollars per pound.

The cashews price was 3%2A1.7=5.10 dollars per pound.

Almonds: 9 pounds, 3$/pound
Cashews: x pounds, 5.1$/pound
Mixture: x+9 pounds, 4$/pound

%289%2A3%2B5.1x%29%2F%28x%2B9%29=4-----You first want to know how much cashews used before answering the question about the percents.
