At a supermarket, packets of cookies are sold only in boxes of 2. The cost of each box is $14.50. The mass of each packet of cookies is 1.1 kg.
- What is the total mass of 5 such packets of cookies?
- How much would 10 such packets of cookies cost?
(a)
Mass of 1 packet of cookies = 1.1 kg
Mass of 5 packets of cookies
= 5 x 1.1
= 5.5 kg
(b)
Cost of 2 packets of cookies = $14.50
Number of sets of 2 packets in 10 packets of cookies
= 10 ÷ 2
= 5
Cost of 10 packets of cookies
= 5 x 14.50
= $72.50
Answer(s): (a) 5.5 kg; (b) $72.50
