The total mass of 3 bags of bread flour and 7 bags of curry powder is 188 kg. Each bag of bread flour has a mass of 16 kg.
- What is the total mass of 3 bags of bread flour?
- What is the total mass of 7 bags of curry powder?
- If each bag of curry powder has the same mass, what is the mass of 1 bag of curry powder?
(a)
Let the mass of 1 bag of bread flour and curry powder be B and C respectively.
Let 1 bag of bread flour be 1 B.
Let 1 bag of curry powder be 1 C.
3 B + 7 C = 188
1 B = 16
Mass of 3 bags of bread flour
= 3 x 16
= 48 kg
(b)
Mass of 7 bags of curry powder
= 188 - 48
= 140 kg
(c)
Mass of 1 bag of curry powder
= 140 ÷ 7
= 20 kg
Answer(s): (a) 48 kg; (b) 140 kg; (c) 20 kg
