Sociologists have found that information spreads among a population at an exponential rate. Suppose function y=52591-e^-0.038t) models the number of people in a town of 525 people who have heard bad news within t hours of its distribution.

Use graphing calculator to graph y=525(1-e^-0.038t) and determine when 90% of people will have heard about the grocery store opening
