At a supermarket, packets of coffee powder are sold only in boxes of 2. The cost of each box is $3.30. The mass of each packet of coffee powder is 2.6 kg.
- What is the total mass of 3 such packets of coffee powder?
- How much would 8 such packets of coffee powder cost?
(a)
Mass of 1 packet of coffee powder = 2.6 kg
Mass of 3 packets of coffee powder
= 3 x 2.6
= 7.8 kg
(b)
Cost of 2 packets of coffee powder = $3.30
Number of sets of 2 packets in 8 packets of coffee powder
= 8 ÷ 2
= 4
Cost of 8 packets of coffee powder
= 4 x 3.30
= $13.20
Answer(s): (a) 7.8 kg; (b) $13.20
