Cashews cost $8.00 per pound, and pecans cost $14.00 per pound. Sandy purchased a total of 12 pounds of these nuts and paid $10.50 per pound. How many pounds

Question

How many pounds of pecans did she purchase?

Answer 1

let c = cashews and p = pecans

Total pounds = c + p = 12 with c = 12-p

We can solve for lbs of pecans by substituting the value of c into the equation 8c + 14p = 10.50 (12)

8(12-p) + 14p = 126

p = 5 lbs
