At a shop, packets of biscuits are sold only in boxes of 3. The cost of each box is $12.60. The mass of each packet of biscuits is 1.2 kg.
- What is the total mass of 8 such packets of biscuits?
- How much would 12 such packets of biscuits cost?
(a)
Mass of 1 packet of biscuits = 1.2 kg
Mass of 8 packets of biscuits
= 8 x 1.2
= 9.6 kg
(b)
Cost of 3 packets of biscuits = $12.60
Number of sets of 3 packets in 12 packets of biscuits
= 12 ÷ 3
= 4
Cost of 12 packets of biscuits
= 4 x 12.60
= $50.40
Answer(s): (a) 9.6 kg; (b) $50.40
