At a shop, packets of tea bags are sold only in boxes of 4. The cost of each box is $14.70. The mass of each packet of tea bags is 2.1 kg.
- What is the total mass of 6 such packets of tea bags?
- How much would 12 such packets of tea bags cost?
(a)
Mass of 1 packet of tea bags = 2.1 kg
Mass of 6 packets of tea bags
= 6 x 2.1
= 12.6 kg
(b)
Cost of 4 packets of tea bags = $14.70
Number of sets of 4 packets in 12 packets of tea bags
= 12 ÷ 4
= 3
Cost of 12 packets of tea bags
= 3 x 14.70
= $44.10
Answer(s): (a) 12.6 kg; (b) $44.10
