The total mass of 5 packets of chicken powder and 4 packets of flour is 178 kg. Each packet of chicken powder has a mass of 14 kg.
- What is the total mass of 5 packets of chicken powder?
- What is the total mass of 4 packets of flour?
- If each bag of flour has the same mass, what is the mass of 1 packet of flour?
(a)
Let the mass of 1 packet of chicken powder and flour be C and F respectively.
Let 1 packet of chicken powder be 1 C.
Let 1 packet of flour be 1 F.
5 C + 4 F = 178
1 C = 14
Mass of 5 packets of chicken powder
= 5 x 14
= 70 kg
(b)
Mass of 4 packets of flour
= 178 - 70
= 108 kg
(c)
Mass of 1 packet of flour
= 108 ÷ 4
= 27 kg
Answer(s): (a) 70 kg; (b) 108 kg; (c) 27 kg
