At a supermarket, packets of tea bags are sold only in boxes of 2. The cost of each box is $4.70. The mass of each packet of tea bags is 2.7 kg.
- What is the total mass of 8 such packets of tea bags?
- How much would 4 such packets of tea bags cost?
(a)
Mass of 1 packet of tea bags = 2.7 kg
Mass of 8 packets of tea bags
= 8 x 2.7
= 21.6 kg
(b)
Cost of 2 packets of tea bags = $4.70
Number of sets of 2 packets in 4 packets of tea bags
= 4 ÷ 2
= 2
Cost of 4 packets of tea bags
= 2 x 4.70
= $9.40
Answer(s): (a) 21.6 kg; (b) $9.40
