Question

An outdoor swimming pool cost $8 per day to visit during the summer. There is also a $25 yearly registration fee. Is the total cost proportional to the total number of days visited ?

Answer 1

365 days taken as a year, the $25.00 per year is only about 7 cents a day for the whole year. Summer is 3 months or 90 days on a normal year and 91 days on a leap year. Take the 90 days summer with a visit every day and that is $720 for the whole summer just for the visits. If you think the $25 yearly fee is paying just for the summer even though you paid for the year but don't use the pool any other time, then cost per year of registration just for the 90 days is about 28 cent a day. Total cost for the 90 days of use for the pool is $720 plus $25 yearly registration fee equals $745 for only 90 days use of pool per year.

Answer 2
