The total mass of 2 packets of chicken powder and 8 packets of pepper is 156 kg. Each packet of chicken powder has a mass of 14 kg.
- What is the total mass of 2 packets of chicken powder?
- What is the total mass of 8 packets of pepper?
- If each bag of pepper has the same mass, what is the mass of 1 packet of pepper?
(a)
Let the mass of 1 packet of chicken powder and pepper be C and P respectively.
Let 1 packet of chicken powder be 1 C.
Let 1 packet of pepper be 1 P.
2 C + 8 P = 156
1 C = 14
Mass of 2 packets of chicken powder
= 2 x 14
= 28 kg
(b)
Mass of 8 packets of pepper
= 156 - 28
= 128 kg
(c)
Mass of 1 packet of pepper
= 128 ÷ 8
= 16 kg
Answer(s): (a) 28 kg; (b) 128 kg; (c) 16 kg
