a business lady leaves her laundry every Monday, then picks it up the next monday as she drops off more. If she wears a clean blouse every day of the week, how many blouses must she have, in order to visit the laundry only on Mondays?
Doesn't she need a minimum of 8 blouses?
To understand how many blouses the business lady needs, let's break down the scenario and calculate the required number.
First, we know that the business lady drops off her laundry every Monday and picks it up the following Monday. This means that she wears each blouse for a duration of one week.
In order to visit the laundry only on Mondays, she needs enough blouses to last her for the entire week until the next visit. So, we need to determine how many days there are between two Mondays.
There are seven days in a week, so the number of blouses needed should be one less than the number of days between two Mondays. This is because she will wear one blouse on the first day and another blouse on the last day before picking up the clean laundry.
Let's calculate the number of days between two Mondays:
Number of days in a week = 7
Number of days to consider = 7 - 1 (since she wears a clean blouse every day except the last)
= 6
Therefore, the business lady needs a minimum of 6 blouses to visit the laundry only on Mondays and wear a clean blouse every day of the week.
