The Miramar Theater chain has studied its movie customers to determine how much money they spend on concessions. The study revealed that the spending distribution is approximately normally distributed with a mean of PhP200.00 and a standard deviation of PhP55.00. What percentage of customers will spend less than PhP150.00 on concessions? Answer must be in percentage form.
