At a supermarket, packets of tea are sold only in boxes of 2. The cost of each box is $6.80. The mass of each packet of tea is 2.7 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 = 2.7 kg
Mass of 7 packets of tea
= 7 x 2.7
= 18.9 kg
(b)
Cost of 2 packets of tea = $6.80
Number of sets of 2 packets in 6 packets of tea
= 6 ÷ 2
= 3
Cost of 6 packets of tea
= 3 x 6.80
= $20.40
Answer(s): (a) 18.9 kg; (b) $20.40
