At a shop, packets of tea are sold only in boxes of 4. The cost of each box is $13.80. The mass of each packet of tea is 1.7 kg.
- What is the total mass of 8 such packets of tea?
- How much would 8 such packets of tea cost?
(a)
Mass of 1 packet of tea = 1.7 kg
Mass of 8 packets of tea
= 8 x 1.7
= 13.6 kg
(b)
Cost of 4 packets of tea = $13.80
Number of sets of 4 packets in 8 packets of tea
= 8 ÷ 4
= 2
Cost of 8 packets of tea
= 2 x 13.80
= $27.60
Answer(s): (a) 13.6 kg; (b) $27.60
