The total mass of 3 bags of sugar and 8 bags of pepper is 223 kg. Each bag of sugar has a mass of 13 kg.
- What is the total mass of 3 bags of sugar?
- What is the total mass of 8 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.
3 S + 8 P = 223
1 S = 13
Mass of 3 bags of sugar
= 3 x 13
= 39 kg
(b)
Mass of 8 bags of pepper
= 223 - 39
= 184 kg
(c)
Mass of 1 bag of pepper
= 184 ÷ 8
= 23 kg
Answer(s): (a) 39 kg; (b) 184 kg; (c) 23 kg
