Leticia invests $200 at 5% interest. if y represents the amount of money after x time periods, which describes the graph of the exponential function relating time and money? the initial value of the graph is 200. the graph increases by a factor of 1.05 per 1 unit increase in time. the initial value of the graph is 200. the graph increases by a factor of 5 per 1 unit increase in time. the initial value of the graph is 500. the graph increases by a factor of 2 per 1 unit increase in time. the initial value of the graph is 500. the graph increases by a factor of 1.02 per 1 unit increase in time.
the answer is a
