The total mass of 2 bags of sugar and 5 bags of chicken powder is 170 kg. Each bag of sugar has a mass of 15 kg.
- What is the total mass of 2 bags of sugar?
- What is the total mass of 5 bags of chicken powder?
- If each bag of chicken powder has the same mass, what is the mass of 1 bag of chicken powder?
(a)
Let the mass of 1 bag of sugar and chicken powder be S and C respectively.
Let 1 bag of sugar be 1 S.
Let 1 bag of chicken powder be 1 C.
2 S + 5 C = 170
1 S = 15
Mass of 2 bags of sugar
= 2 x 15
= 30 kg
(b)
Mass of 5 bags of chicken powder
= 170 - 30
= 140 kg
(c)
Mass of 1 bag of chicken powder
= 140 ÷ 5
= 28 kg
Answer(s): (a) 30 kg; (b) 140 kg; (c) 28 kg
