Explanation:

Admission prices to Dollywood are $50 for a one-day ticket, $80 for a two-day ticket, and $100 for an annual pass. Based on these prices, the marginal cost of visiting Dollywood the second day is $30, the third day is $20, and the fourth day is $0.

The marginal cost is the extra cost per day of going to Dollywood.

Second day

Marginal cost = Second day price - First day

= 80 - 50

= $30

Third day

Marginal cost = Third day price - Second day

= 100 - 80

= $20

Fourth Day

Marginal cost = Fourth day price - third day

= 100 - 100

= $0
