Jack rents rooms in his hotel for an average of $100 per night. the variable cost per rented room is $20, to cover maid service and utilities. his fixed costs are $100,000 and his profit last year was $20,000. for jack, the contribution per unit

$80 per unit

Explanation:

We know that,

Contribution per unit = Selling price per unit - variable cost per unit

                                   = $100 per night - $20 per rented room

                                   = $80 per unit

Simply we deduct the variable cost per unit from the Selling price per unit so that the contribution margin can be computed
