At a shop, packets of tea are sold only in boxes of 2. The cost of each box is $9.60. The mass of each packet of tea is 2.1 kg.
- What is the total mass of 2 such packets of tea?
- How much would 8 such packets of tea cost?
(a)
Mass of 1 packet of tea = 2.1 kg
Mass of 2 packets of tea
= 2 x 2.1
= 4.2 kg
(b)
Cost of 2 packets of tea = $9.60
Number of sets of 2 packets in 8 packets of tea
= 8 ÷ 2
= 4
Cost of 8 packets of tea
= 4 x 9.60
= $38.40
Answer(s): (a) 4.2 kg; (b) $38.40
