The total mass of 2 bags of pepper and 6 bags of chilli powder is 158 kg. Each bag of pepper has a mass of 13 kg.
- What is the total mass of 2 bags of pepper?
- What is the total mass of 6 bags of chilli powder?
- If each bag of chilli powder has the same mass, what is the mass of 1 bag of chilli powder?
(a)
Let the mass of 1 bag of pepper and chilli powder be P and C respectively.
Let 1 bag of pepper be 1 P.
Let 1 bag of chilli powder be 1 C.
2 P + 6 C = 158
1 P = 13
Mass of 2 bags of pepper
= 2 x 13
= 26 kg
(b)
Mass of 6 bags of chilli powder
= 158 - 26
= 132 kg
(c)
Mass of 1 bag of chilli powder
= 132 ÷ 6
= 22 kg
Answer(s): (a) 26 kg; (b) 132 kg; (c) 22 kg
