The lowest charge of the two parks you have to spend for staying four or more nights.
Explanation of Solution
Given information:
Park A charges a
Park B charges a
Calculations:
Let the number of days spend be
Therefore charges for park A is
Similarly charges for park B is
Now if,
Therefore we can see that if a person stays for four days then he has to spend equal amount for both the parks in which he stays.
If a person stays for less than four days then he has to spend more money if he stays in park A than park B.
If a person stays for more than four days then he has to less more money if he stays in park A than park B.
Let us check,
Let the number of days spend be
Therefore charges for park A is
Similarly charges for park B is
So, charges for park A is more than charges for park B for
Let the number of days spend be
Therefore charges for park A is
Similarly charges for park B is
So, charges for park A are equal to charges for park B for
Let the number of days spend be
Therefore charges for park A is
Similarly charges for park B is
So, charges for park A are less than charges for park B for
Thus it is checked.
