At a shop, packets of cocoa beans are sold only in boxes of 2. The cost of each box is $7.10. The mass of each packet of cocoa beans is 2.3 kg.
- What is the total mass of 8 such packets of cocoa beans?
- How much would 10 such packets of cocoa beans cost?
(a)
Mass of 1 packet of cocoa beans = 2.3 kg
Mass of 8 packets of cocoa beans
= 8 x 2.3
= 18.4 kg
(b)
Cost of 2 packets of cocoa beans = $7.10
Number of sets of 2 packets in 10 packets of cocoa beans

= 5
Cost of 10 packets of cocoa beans
= 5 x 7.10
= $35.50
Answer(s): (a) 18.4 kg; (b) $35.50
