Question

cashew nuts sell for $21.00/kg. Brazil nuts sell for $15.00/k. A distributor sold a total of 120 kg of nuts and Brazil nuts for $2244. What mass of each type of nut was sold?

Answer 1

c + b =120
21c +1

Answer 2

c + b =120
21c +15b = 2244

c = 120-b

21(120-b ) + 15b = 2244

2520 -21b + 15b = 2244

2520 -6b = 2244

2520-2520 -6b = 2244-2520

-6b = -276

b = 46

c = 120 -46

c = 74
Cashew nuts = 74kg
Brazil nuts = 46kg

Answer 3

Thanks!
