Question

To make a special mix, the owner of a fruit stand wants to combine cashews that sell for $7.00 per lb with walnuts that sell for $5.50 per lb to obtain a 35 lb hat sells for $6.50 per lb. How many pounds of each type of nut should be used in the mixture?

adding up the value of each part needs to equal the value of the total mixture. So, if x lbs of cashews are used,

7.00x + 5.50(35-x) = 6.50(35)
x = 23 1/3 lbs cashews
