The total mass of 8 bags of pepper and 3 bags of flour is 198 kg. Each bag of pepper has a mass of 15 kg.
- What is the total mass of 8 bags of pepper?
- What is the total mass of 3 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 pepper and flour be P and F respectively.
Let 1 bag of pepper be 1 P.
Let 1 bag of flour be 1 F.
8 P + 3 F = 198
1 P = 15
Mass of 8 bags of pepper
= 8 x 15
= 120 kg
(b)
Mass of 3 bags of flour
= 198 - 120
= 78 kg
(c)
Mass of 1 bag of flour
= 78 ÷ 3
= 26 kg
Answer(s): (a) 120 kg; (b) 78 kg; (c) 26 kg
