At a shop, packets of cocoa beans are sold only in boxes of 2. The cost of each box is $14.80. The mass of each packet of cocoa beans is 1.8 kg.
- What is the total mass of 9 such packets of cocoa beans?
- How much would 8 such packets of cocoa beans cost?
(a)
Mass of 1 packet of cocoa beans = 1.8 kg
Mass of 9 packets of cocoa beans
= 9 x 1.8
= 16.2 kg

= 4
Cost of 8 packets of cocoa beans
