Hello students, we are given a question here.
00:02
Every month, frank pays an $80 membership fee at a fitness center so that he can avail himself of the unlimited use of its facilities.
00:14
On the average, he goes to the center 10 times a month.
00:19
Okay, students, now we are asked about the marginal cost of an additional workout session.
00:25
So we are supposed to know that here we need to find first of all the average cost.
00:31
So average cost is equal to we can say that the total cost.
00:38
In this case we can say that it is the membership fees.
00:43
Membership fee divided by number of visits, number of tours of or visits.
00:53
Okay, students, membership fee is given as $80.
00:57
So we can write here $80 divided by number of visits 10 times a month.
01:02
So 10, it means it is $8 per month...
