1. Determine the standard of holiday meal fee first: Beijing regulations stipulate that the standard of kindergarten holiday meal fee is 15 yuan per person per day.

2. Determine the number of meal days: According to the arrangement of the kindergarten and the demand of the parents, determine the number of days that the children need to eat during the holidays.

3. Calculate the cost of meals: multiply the number of days of meals by the cost of meals per person per day to get the cost of meals that the child needs to pay during the holidays.
