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 cashews should he use?
+36916 10 pound mixture
c = cashews cost 6.50 c
p = peanuts = 10-c cost = 4.00p(10-c) summed = 10 (4.75)
6.5 c + 4(10-c) = 10 (4.75 )
solve for 'c' the pounds of cashews, then pounds of peanuts = 10-c
