The total mass of 4 bags of bread flour and 7 bags of pepper is 278 kg. Each bag of bread flour has a mass of 17 kg.
- What is the total mass of 4 bags of bread flour?
- What is the total mass of 7 bags of pepper?
- If each bag of pepper has the same mass, what is the mass of 1 bag of pepper?
(a)
Let the mass of 1 bag of bread flour and pepper be B and P respectively.
Let 1 bag of bread flour be 1 B.
Let 1 bag of pepper be 1 P.
4 B + 7 P = 278
1 B = 17
Mass of 4 bags of bread flour
= 4 x 17
= 68 kg
(b)
Mass of 7 bags of pepper
= 278 - 68
= 210 kg
(c)
Mass of 1 bag of pepper
= 210 ÷ 7
= 30 kg
Answer(s): (a) 68 kg; (b) 210 kg; (c) 30 kg
