At a supermarket, packets of biscuits are sold only in boxes of 2. The cost of each box is $5.70. The mass of each packet of biscuits is 2.4 kg.
- What is the total mass of 2 such packets of biscuits?
- How much would 8 such packets of biscuits cost?
(a)
Mass of 1 packet of biscuits = 2.4 kg
Mass of 2 packets of biscuits
= 2 x 2.4
= 4.8 kg
(b)
Cost of 2 packets of biscuits = $5.70
Number of sets of 2 packets in 8 packets of biscuits
= 8 ÷ 2
= 4
Cost of 8 packets of biscuits
= 4 x 5.70
= $22.80
Answer(s): (a) 4.8 kg; (b) $22.80
