<PRE><B>Question 718888</B>
The manager of a bulk foods establishment sells peanuts for $8 per pound and premium cashews for $15 per pound. The manager wishes to make a 35 pound nut mixture that will sell for $14 per pound. How many pounds of peanuts should be used?
***
let x=amount of peanuts to use
35-x=amount of cashews to use
..
8x+15(35-x)=35(14)
8x+525-15x=490
7x=35
x=5
35-x=30
amount of peanuts to use=5 pounds
amount of cashews to use=30 pounds</PRE>
