The total mass of 5 packets of chicken powder and 5 packets of pepper is 220 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 5 packets of pepper?
- If each bag of pepper has the same mass, what is the mass of 1 packet of pepper?
(a)
Let the mass of 1 packet of chicken powder and pepper be C and P respectively.
Let 1 packet of chicken powder be 1 C.
Let 1 packet of pepper be 1 P.
5 C + 5 P = 220
1 C = 14
Mass of 5 packets of chicken powder
= 5 x 14
= 70 kg
(b)
Mass of 5 packets of pepper
= 220 - 70
= 150 kg
(c)
Mass of 1 packet of pepper
= 150 ÷ 5
= 30 kg
Answer(s): (a) 70 kg; (b) 150 kg; (c) 30 kg
