The total mass of 2 packets of chicken powder and 5 packets of flour is 160 kg. Each packet of chicken powder has a mass of 15 kg.
- What is the total mass of 2 packets of chicken powder?
- What is the total mass of 5 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.
2 C + 5 F = 160
1 C = 15
Mass of 2 packets of chicken powder
= 2 x 15
= 30 kg
(b)
Mass of 5 packets of flour
= 160 - 30
= 130 kg
(c)
Mass of 1 packet of flour
= 130 ÷ 5
= 26 kg
Answer(s): (a) 30 kg; (b) 130 kg; (c) 26 kg
