A recent survey by the American Automobile Association showed that a family of two adults and two children on vacation in the United States will pay an average of $247 per day for food and lodging with a standard deviation of $60 per day. Assuming the data are normally distributed, if the family had a z-score of 1.5, what was their daily expense for food and lodging? If the data are normally distributed, find the percentage of these families who spent:
