The total mass of 8 packets of chilli powder and 3 packets of sugar is 176 kg. Each packet of chilli powder has a mass of 13 kg.
- What is the total mass of 8 packets of chilli powder?
- What is the total mass of 3 packets of sugar?
- If each bag of sugar has the same mass, what is the mass of 1 packet of sugar?
(a)
Let the mass of 1 packet of chilli powder and sugar be C and S respectively.
Let 1 packet of chilli powder be 1 C.
Let 1 packet of sugar be 1 S.
8 C + 3 S = 176
1 C = 13
Mass of 8 packets of chilli powder
= 8 x 13
= 104 kg
(b)
Mass of 3 packets of sugar
= 176 - 104
= 72 kg
(c)
Mass of 1 packet of sugar
= 72 ÷ 3
= 24 kg
Answer(s): (a) 104 kg; (b) 72 kg; (c) 24 kg
