Substitute the given values in the formula A = Pe" to find the missing quantity. 6. P = 680,000; r = 12% per year; 1 = 8 years 7. A = 1.240.000; r = 8% per year, 1 = 30 years 8. A = 786.000; P = 247,000; 1 = 17 years 9. A = 731,093, P 525.600; r = 3% per year Answer completely. 10. Suppose the population of a certain bacteria in a laboratory sample is 100. If it doubles in population every 6 hours, what is the growth rate? How many bacteria will there be in two days
