Question
D. At your local family fun center, miniature golf is $12 per person for an unlimited number of rounds in a day, while each go-kart session is $8.
The total cost of playing 2 rounds of miniature golf is $j/pMivnfBklIiAe+nWAbqDXy+DY= and the total cost of playing 3 rounds of miniature golf is $j/pMivnfBklIiAe+nWAbqDXy+DY=. The marginal cost for the third round of golf is $kK+qU2aHQayN5BW/nGWD0OeU2nY=.
Correct! Since after paying $12 you can play an unlimited number of rounds of miniature golf, the total cost of playing 2 rounds is the same as playing three rounds. Therefore, the marginal cost to play a third round is $0.
Incorrect. Remember, the marginal cost is just the additional cost. Since after paying $12 you can play an unlimited number of rounds of miniature golf, the total cost to play 2 rounds is the same as the cost to play three rounds. Therefore, the marginal cost to play the third round is $0.

E. The total cost of 2 go-kart sessions is $

Correct! The total cost for 2 go-kart sessions is $8 × 2 = $16. The total cost for 3 go-kart sessions is $8 × 3 = $24. The marginal cost is the additional cost to ride a go-kart one more time. Thus, the marginal cost for the third session can be calculated by subtracting the total cost for three sessions by the total cost for two sessions, $24 – $16 = $8.
