i need every step of all calculations

1. Let pe denote the size of the U.S. population (in millions) at time t. Suppose the population increases by o percent per year. Let Pe denote the size of the population at time 0. Let Po = 300 million. (a) Write the expression for Pl as a function of po, B, and t. Show every step of all calculations. (b) Use the expression in part(a) to compute the size of the population at time t = 5 if p = 3 percent. Show every step of all calculations. (c) Calculate exactly how many years it will take for the population to increase to 600 million if p = 3 percent. Show every step of all calculation (d) Suppose the population increased from 300 million at timet -0 to 300 million at timet - 20. Calculate the average population growth rate between those two time periods. Show every step of all calculations. (e) let po = 300 million and p = 3 percent. Plot the size of the population on a standard scale when you let time to from 0 to 30 on the horizontal axis ( Make the same graph on a ratio scale
