The local government is planning to give financial assistance to low income families in remote barangays due to COVID-19 crisis. To be successful in this endeavor, the mayor instructed his staff to conduct a survey in order to determine the monthly income of each family. After surveying 500 families, the staff found out that the monthly income of the families is normally distributed with a mean of P5,200 and a standard deviation of P400. If the mayor will only give financial assistance to families whose monthly income is at most P5000, How many families will receive the financial assistance?
