The total mass of 2 packets of chicken powder and 9 packets of bread flour is 245 kg. Each packet of chicken powder has a mass of 19 kg.
- What is the total mass of 2 packets of chicken powder?
- What is the total mass of 9 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 chicken powder and bread flour be C and B respectively.
Let 1 packet of chicken powder be 1 C.
Let 1 packet of bread flour be 1 B.
2 C + 9 B = 245
1 C = 19
Mass of 2 packets of chicken powder
= 2 x 19
= 38 kg
(b)
Mass of 9 packets of bread flour
= 245 - 38
= 207 kg
(c)
Mass of 1 packet of bread flour
= 207 ÷ 9
= 23 kg
Answer(s): (a) 38 kg; (b) 207 kg; (c) 23 kg
