At a shop, packets of biscuits are sold only in boxes of 2. The cost of each box is $11.70. The mass of each packet of biscuits is 2.8 kg.
- What is the total mass of 3 such packets of biscuits?
- How much would 6 such packets of biscuits cost?
(a)
Mass of 1 packet of biscuits = 2.8 kg
Mass of 3 packets of biscuits
= 3 x 2.8
= 8.4 kg
(b)
Cost of 2 packets of biscuits = $11.70
Number of sets of 2 packets in 6 packets of biscuits
= 6 ÷ 2

Cost of 6 packets of biscuits

= $35.10
Answer(s): (a) 8.4 kg; (b) $35.10
