An appropriate choice of outdoor play equipment for a toddler play yard would be a small wooden playhouse. This is so because it helps them improve their health through using lots of energy which could be a good amount of exercise. Another reason is that it will improve their social skills. Since they will be talking and interacting with their playmates, their social skills will be properly honed. This will also help them become responsible because of the rules set on the playhouse.
Answer:
Given that,
Operator bought a futures contract = 5,000 kilograms of rice at $1.50 per kilogram
Initial margin = $4,000
Maintenance margin = $2,000
(a)
(i) Balance of Margin = Initial margin - maintenance margin
= $4,000 - $2,000
= $2,000 (loss)
(ii) Change in price = 
= $0.40
(b) Price per kilogram = Current price - Change in Price
= $1.50 - $0.40
= $1.10
So, change price per kg is $1.10
(c) Balance of Margin = Initial margin - maintenance margin
= $4,000 + $2,000
= $6,000 (loss)
Change in price = 
= $0.40
(d) Price per kg = Current price - change in price
= $1.50 + $0.40
= $1.90
Answer: Harder to sustain cooperation
Explanation:
When the number of firms in an oligopolistic market increases as is the case here, cooperation becomes harder because profits become smaller so companies start to become more selfish.
Also in this scenario, the cheating firm has the incentive to do so because the profit is so much higher than sharing so companies will always be looking to cheat in order to make this profit. The other firms would reply by reducing prices and all of them would suffer.
