At a shop, packets of tea are sold only in boxes of 2. The cost of each box is $13.90. The mass of each packet of tea is 1.6 kg.
- What is the total mass of 7 such packets of tea?
- How much would 6 such packets of tea cost?
(a)
Mass of 1 packet of tea = 1.6 kg
Mass of 7 packets of tea
= 7 x 1.6
= 11.2 kg
(b)
Cost of 2 packets of tea = $13.90
Number of sets of 2 packets in 6 packets of tea
= 6 ÷ 2
= 3
Cost of 6 packets of tea
= 3 x 13.90
= $41.70
Answer(s): (a) 11.2 kg; (b) $41.70
