Answer and Explanation:
The computation is shown below:
1. The selling price per unit is
Particulars Quantity Selling price Total per composite unit
per unit
Windows 7 $113 $791
Doors 3 $253 $759
Total $1,550
2. The variable cost per unit is
Particulars Quantity Variable cost Total per composite unit
per unit
Windows 7 $69 $483
Doors 3 $181.50 $544.50
Total $1,027.50
The contribution margin per unit is
= Selling price - variable cost
= $1,550 - $1,027.50
= $522.50
3. The break even point is
= Fixed cost ÷ contribution margin per unit
= $469,625 ÷ $522.50
= 898.80 units
4. The number of unit is
Particulars Quantity Variable cost Total per composite unit
per unit
Windows 7 $898.80 $6,291.60
Doors 3 $898.80 $2,694.40
Total $8,988
