At a shop, packets of biscuits are sold only in boxes of 2. The cost of each box is $6.60. The mass of each packet of biscuits is 1.5 kg.
- What is the total mass of 9 such packets of biscuits?
- How much would 4 such packets of biscuits cost?

Mass of 1 packet of biscuits = 1.5 kg
Mass of 9 packets of biscuits
