The total mass of 8 bags of sugar and 3 bags of pepper is 182 kg. Each bag of sugar has a mass of 16 kg.
- What is the total mass of 8 bags of sugar?
- What is the total mass of 3 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 + 3 P = 182
1 S = 16
Mass of 8 bags of sugar
= 8 x 16
= 128 kg
(b)
Mass of 3 bags of pepper
= 182 - 128
= 54 kg
(c)
Mass of 1 bag of pepper
= 54 ÷ 3
= 18 kg
Answer(s): (a) 128 kg; (b) 54 kg; (c) 18 kg
