The total mass of 8 bags of sugar and 4 bags of pepper is 200 kg. Each bag of sugar has a mass of 11 kg.
- What is the total mass of 8 bags of sugar?
- What is the total mass of 4 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 sugar and pepper be S and P respectively.
Let 1 bag of sugar be 1 S.
Let 1 bag of pepper be 1 P.
8 S + 4 P = 200
1 S = 11
Mass of 8 bags of sugar
= 8 x 11
= 88 kg
(b)
Mass of 4 bags of pepper
= 200 - 88
= 112 kg
(c)
Mass of 1 bag of pepper
= 112 ÷ 4
= 28 kg
Answer(s): (a) 88 kg; (b) 112 kg; (c) 28 kg
