Andrew wanted to see how contagious yawning can be. To better understand this, he conducted a social experiment by yawning in front of a random large crowd and observing how many people yawned as a result. The relationship between the elapsed time , in minutes, since Andrew yawned, and the number of people in the crowd, who yawned as a result is modeled by the following function: P_{min}(t)=5⋅(1.04)^t Complete the following sentence about the hourly rate of change in the number of people who yawn in Andrew's experiment. Round your answer to two decimal places. Every hour, the number of people who yawn in Andrew's experiment grows by a factor of:
