At a shop, packets of cocoa beans are sold only in boxes of 4. The cost of each box is $8.90. The mass of each packet of cocoa beans is 1.6 kg.
- What is the total mass of 4 such packets of cocoa beans?
- How much would 8 such packets of cocoa beans cost?
(a)
Mass of 1 packet of cocoa beans = 1.6 kg
Mass of 4 packets of cocoa beans
= 4 x 1.6
= 6.4 kg
(b)
Cost of 4 packets of cocoa beans = $8.90
Number of sets of 4 packets in 8 packets of cocoa beans
= 8 ÷ 4
= 2
Cost of 8 packets of cocoa beans
= 2 x 8.90
= $17.80
Answer(s): (a) 6.4 kg; (b) $17.80
