The total mass of 7 bags of flour and 3 bags of chicken powder is 153 kg. Each bag of flour has a mass of 15 kg.
- What is the total mass of 7 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.
7 F + 3 C = 153
1 F = 15
Mass of 7 bags of flour
= 7 x 15
= 105 kg
(b)
Mass of 3 bags of chicken powder
= 153 - 105
= 48 kg
(c)
Mass of 1 bag of chicken powder
= 48 ÷ 3
= 16 kg
Answer(s): (a) 105 kg; (b) 48 kg; (c) 16 kg
