A grocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4.75 per pound. If peanuts cost $4.00 per pound and cashews cost $6.50 per pound, how many pounds of each should he use? Let p = pounds of peanuts and let c = pounds of cashews. Write a system of equations that could be used to solve the problem.
Making 10 pounds
c = cashews
10-c = peanuts
(10-c) = p
c (6.5) + (10-c)(4.0) = 10 (4.75) solve for c then solve for p with the red equation
