At a shop, packets of tea are sold only in boxes of 4. The cost of each box is $13.40. The mass of each packet of tea is 2.3 kg.
- What is the total mass of 2 such packets of tea?
- How much would 12 such packets of tea cost?
(a)
Mass of 1 packet of tea = 2.3 kg
Mass of 2 packets of tea
= 2 x 2.3
= 4.6 kg
(b)
Cost of 4 packets of tea = $13.40
Number of sets of 4 packets in 12 packets of tea
= 12 ÷ 4
= 3
Cost of 12 packets of tea
= 3 x 13.40
= $40.20
Answer(s): (a) 4.6 kg; (b) $40.20
