4. As the sales grows 12% per month, the present sales would be equal to previous sales multiplied by (1+12%) and etc....., it follows a geometic progressiom. Total annual sales equal 9200[(1.12^13 -1)]/(1.12-1) = $257,867.81.
5. Assume the country takes n year to fall below 1200 unit per person level, The formula : 3600 mil * (1+4%)^n / 2.5 mil * (1+6%)^n < 1200 , 1,440 * (1.04/1.06)^n<1200, n=10. Therefore, the country will take 10 years to fall below minimum recommended average intake of food of 1200 unit of food per person per year.
