At a supermarket, packets of cookies are sold only in boxes of 4. The cost of each box is $8.30. The mass of each packet of cookies is 2.7 kg.
- What is the total mass of 4 such packets of cookies?
- How much would 16 such packets of cookies cost?
(a)
Mass of 1 packet of cookies = 2.7 kg
Mass of 4 packets of cookies
= 4 x 2.7
= 10.8 kg
(b)
Cost of 4 packets of cookies = $8.30
Number of sets of 4 packets in 16 packets of cookies
= 16 ÷ 4
= 4
Cost of 16 packets of cookies
= 4 x 8.30
= $33.20
Answer(s): (a) 10.8 kg; (b) $33.20
