At a shop, packets of tea are sold only in boxes of 2. The cost of each box is $9.70. The mass of each packet of tea is 2.9 kg.
- What is the total mass of 7 such packets of tea?
- How much would 10 such packets of tea cost?
(a)
Mass of 1 packet of tea = 2.9 kg
Mass of 7 packets of tea
= 7 x 2.9
= 20.3 kg
(b)
Cost of 2 packets of tea = $9.70
Number of sets of 2 packets in 10 packets of tea
= 10 ÷ 2
= 5
Cost of 10 packets of tea
= 5 x 9.70
= $48.50
Answer(s): (a) 20.3 kg; (b) $48.50
