Ah Tee sold an average of 147 copies of newspaper per day on weekdays and an average of 217 copies per day on saturday and sunday. Find the average number of copies per day for the whole week.
To find the average number of copies per day for the whole week, we need to take into account the number of weekdays and weekend days in a week.
There are 5 weekdays (Monday to Friday) and 2 weekend days (Saturday and Sunday) in a week.
Average number of copies per day for the whole week = [(147 copies/day * 5 days) + (217 copies/day * 2 days)] / 7 days
= (735 copies + 434 copies) / 7 days
= 1169 copies / 7 days
= 167 copies per day
Therefore, the average number of copies per day for the whole week is 167 copies.
