Hello, can you please help me with those two questions from the CALC book from the chapter of indefinite integrals

A culture of bacteria is growing at the rate of 20e-of cells per day, where & is the number of days since the culture was started. Suppose that the culture began with 50 cells. (a) Find a formula for the total number of cells in the culture after t days. T(() = (b) If the culture is to be stopped when the population reaches 475, when will this occur? (Round your answer to one decimal place.) days
