The total mass of 5 bags of flour and 3 bags of chicken powder is 169 kg. Each bag of flour has a mass of 20 kg.
- What is the total mass of 5 bags of flour?
- What is the total mass of 3 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 flour and chicken powder be F and C respectively.
Let 1 bag of flour be 1 F.
Let 1 bag of chicken powder be 1 C.
5 F + 3 C = 169
1 F = 20
Mass of 5 bags of flour
= 5 x 20
= 100 kg
(b)
Mass of 3 bags of chicken powder
= 169 - 100
= 69 kg
(c)
Mass of 1 bag of chicken powder
= 69 ÷ 3
= 23 kg
Answer(s): (a) 100 kg; (b) 69 kg; (c) 23 kg
