At a supermarket, packets of cocoa beans are sold only in boxes of 2. The cost of each box is $10.90. The mass of each packet of cocoa beans is 2.5 kg.
- What is the total mass of 7 such packets of cocoa beans?
- How much would 8 such packets of cocoa beans cost?
(a)
Mass of 1 packet of cocoa beans = 2.5 kg
Mass of 7 packets of cocoa beans
= 7 x 2.5
= 17.5 kg
(b)
Cost of 2 packets of cocoa beans = $10.90
Number of sets of 2 packets in 8 packets of cocoa beans
= 8 ÷ 2
= 4
Cost of 8 packets of cocoa beans
= 4 x 10.90
= $43.60
Answer(s): (a) 17.5 kg; (b) $43.60
