Sally did an experiment. She started out with 250 bacteria cells. She found that the hourly growth rate of the bacteria cells was 4.1%. Using the exponential growth formula, y=b〖(1+r)〗^t, sketch the graph that represents the situation. Label the axes, y-intercept, and the point that represents the projected bacteria population 25 hours from the time Sally started the experiment.
