The total mass of 8 bags of sugar and 2 bags of flour is 204 kg. Each bag of sugar has a mass of 18 kg.
- What is the total mass of 8 bags of sugar?
- What is the total mass of 2 bags of flour?
- If each bag of flour has the same mass, what is the mass of 1 bag of flour?
(a)
Let the mass of 1 bag of sugar and flour be S and F respectively.
Let 1 bag of sugar be 1 S.
Let 1 bag of flour be 1 F.
8 S + 2 F = 204
1 S = 18
Mass of 8 bags of sugar
= 8 x 18
= 144 kg
(b)
Mass of 2 bags of flour
= 204 - 144
= 60 kg
(c)
Mass of 1 bag of flour
= 60 ÷ 2
= 30 kg
Answer(s): (a) 144 kg; (b) 60 kg; (c) 30 kg
