Both direct materials and rent expense are variable costs. b.Utilities expense is a mixed cost and rent expense is a variable cost. c.Utilities expense is a mixed cost and rent expense is a fixed cost. d.Direct materials is a fixed cost and utilities expense is a mixed cost. e.Both direct materials and utilities expense are mixed costs.

c.Utilities expense is a mixed cost and rent expense is a fixed cost

Explanation:

Based on the information:

                              1,000 units of output     5,000 units of output

                              Total       Cost/Unit          Total     Cost/Unit

Direct materials      $5,000   $5.00             $25,000  $5.00

Utilities expense    $1,000     $1.00              $3,750     $0.75

Rent expense        $4,000     $4.00             $4,000    $0.80

Total Rent expense remains constant at 5,000 units of output as it is at 1,000 units of output ($4,000). So we know that rent expense is a fixed cost for Seacrest Enterprises.

Utilities expense has changed at 5,000 units of output so it is not a fixed cost and the cost/unit has also decreased to $0.75 so it is a mixed cost.

So now we look at all the given options:

a.Both direct materials and rent expense are variable costs. (wrong, as rent expense is not a variable cost but a fixed cost)

b.Utilities expense is a mixed cost and rent expense is a variable cost.

(wrong, as rent expense is not a variable cost but a fixed cost)

c.Utilities expense is a mixed cost and rent expense is a fixed cost. (CORRECT)

d.Direct materials is a fixed cost and utilities expense is a mixed cost. (wrong,direct material is not a fixed cost since it has increased at 5000 units of output)

e.Both direct materials and utilities expense are mixed costs. (direct material is not a mixed cost but a variable cost)
