The total mass of 8 packets of curry powder and 4 packets of bread flour is 196 kg. Each packet of curry powder has a mass of 17 kg.
- What is the total mass of 8 packets of curry powder?
- What is the total mass of 4 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 curry powder and bread flour be C and B respectively.
Let 1 packet of curry powder be 1 C.
Let 1 packet of bread flour be 1 B.
8 C + 4 B = 196
1 C = 17
Mass of 8 packets of curry powder
= 8 x 17
= 136 kg
(b)
Mass of 4 packets of bread flour
= 196 - 136
= 60 kg
(c)
Mass of 1 packet of bread flour
= 60 ÷ 4
= 15 kg
Answer(s): (a) 136 kg; (b) 60 kg; (c) 15 kg
