The total mass of 8 bags of chicken powder and 3 bags of rice flour is 161 kg. Each bag of chicken powder has a mass of 19 kg.
- What is the total mass of 8 bags of chicken powder?
- What is the total mass of 3 bags of rice flour?
- If each bag of rice flour has the same mass, what is the mass of 1 bag of rice flour?
(a)
Let the mass of 1 bag of chicken powder and rice flour be C and R respectively.
Let 1 bag of chicken powder be 1 C.
Let 1 bag of rice flour be 1 R.
8 C + 3 R = 161
1 C = 19
Mass of 8 bags of chicken powder
= 8 x 19
= 152 kg
(b)
Mass of 3 bags of rice flour
= 161 - 152
= 9 kg
(c)
Mass of 1 bag of rice flour
= 9 ÷ 3
= 3 kg
Answer(s): (a) 152 kg; (b) 9 kg; (c) 3 kg
