The total mass of 3 packets of sugar and 4 packets of bread flour is 164 kg. Each packet of sugar has a mass of 16 kg.
- What is the total mass of 3 packets of sugar?
- What is the total mass of 4 packets of bread flour?
- If each bag of bread flour has the same mass, what is the mass of 1 packet of bread flour?
(a)
Let the mass of 1 packet of sugar and bread flour be S and B respectively.
Let 1 packet of sugar be 1 S.
Let 1 packet of bread flour be 1 B.
3 S + 4 B = 164
1 S = 16
Mass of 3 packets of sugar
= 3 x 16
= 48 kg
(b)
Mass of 4 packets of bread flour
= 164 - 48
= 116 kg
(c)
Mass of 1 packet of bread flour
= 116 ÷ 4
= 29 kg
Answer(s): (a) 48 kg; (b) 116 kg; (c) 29 kg
