The total mass of 4 packets of pepper and 6 packets of bread flour is 194 kg. Each packet of pepper has a mass of 17 kg.
- What is the total mass of 4 packets of pepper?
- What is the total mass of 6 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 pepper and bread flour be P and B respectively.
Let 1 packet of pepper be 1 P.
Let 1 packet of bread flour be 1 B.
4 P + 6 B = 194
1 P = 17
Mass of 4 packets of pepper
= 4 x 17
= 68 kg
(b)
Mass of 6 packets of bread flour
= 194 - 68
= 126 kg
(c)
Mass of 1 packet of bread flour
= 126 ÷ 6
= 21 kg
Answer(s): (a) 68 kg; (b) 126 kg; (c) 21 kg
