Question
A library has an average of 510 visitors on Sundays and 240 on other days. The average number of visitors per day in a month of 30 days beginning with a Sunday is:250276280285
Solution
The problem can be solved in the following steps:
Step 1: Calculate the total number of Sundays in a month that begins with a Sunday. In a 30-day month, there are 4 Sundays and 26 other days.
Step 2: Calculate the total number of visitors on Sundays. The library has an average of 510 visitors on Sundays. So, the total number of visitors on Sundays is 510 * 4 = 2040.
Step 3: Calculate the total number of visitors on other days. The library has an average of 240 visitors on other days. So, the total number of visitors on other days is 240 * 26 = 6240.
Step 4: Calculate the total number of visitors in the month. The total number of visitors in the month is the sum of the total number of visitors on Sundays and the total number of visitors on other days. So, the total number of visitors in the month is 2040 + 6240 = 8280.
Step 5: Calculate the average number of visitors per day in the month. The average number of visitors per day in the month is the total number of visitors in the month divided by the number of days in the month. So, the average number of visitors per day in the month is 8280 / 30 = 276.
So, the average number of visitors per day in a month of 30 days beginning with a Sunday is 276.
