We determine that An Binh company’s investment in the Mekong Delta in the first quarter is VND 78 billion

Similarly, we can determine the amount of investment in the Mekong Delta of An Binh company in Quarter II, Quarter III, Quarter IV respectively: 45, 25, 35 (billion VND)

c) We have the following table:

 Precious First quarter Second quarter Third quarter Fourth quarter Amount of investment in the Red River Delta (billion VND) 62 55 35 sixty one Amount of investment in the Mekong Delta (billion VND) 78 45 25 35
