Question

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?
