Sherman peabody earns a monthly salary of $2000, which he receives at the beginning of each month. he spends the entire amount each month, at the rate of $67 per day. (assume 30 days in a month.) the interest rate paid on bonds is 10 percent per month. it costs $4 every time peabody sells a bond. using the information above compute the following: (1) peabody should sell (switch) bonds per month, because he can maximize his net profit by doing so. (enter your response as an ) the maximum net profit would be $ (enter your response as an ) the optimal average of money holdings is $

The biologist has a second culture to examine. she knows that the population of the culture doubles every 15 minutes. after 1 hour and 15 minutes, her assistant found that 80,000 bacteria were present. a) what was the size of the initial population? b) predict the size of the culture at t=3 hours. what was the size of the population at 40 minutes? explain and justify your answers. c) create a graph of the population as a function of time. find an equation that can be used to predict the size of the population at any time t. d) examine the rate at which the bacteria culture is growing. how fast is the culture growing after 1 hour? after 1.5 hours? after 2 hours? use a time interval of h = 0.01 hours to estimate these rates. interpret these rates in terms of the context of the problem situation. how do these three rates compare?
