Let's assume GDPs for US and China at the beginning of 2016 are US$ 18 trillion and US$ 11.4 trillion. If the GDP growth rates for US and China are 1.9% and 6.7% for years to come, from the beginning of 2016, how many more years would it take for China to catch up with the US' GDP? (rounding at 10000th, e. g. .43568 -> .4357; .02634 -> .0263)

Two products, qi and vh, emerge from a joint process. product qi has been allocated $34,300 of the total joint costs of $55,000. a total of 2,900 units of product qi are produced from the joint process. product qi can be sold at the split-off point for $11 per unit, or it can be processed further for an additional total cost of $10,900 and then sold for $13 per unit. if product qi is processed further and sold, what would be the financial advantage (disadvantage) for the company compared with sale in its unprocessed form directly after the split-off point?
