Answer:
weighted-average contribution margin= $4.7
Explanation:
Giving the following information:
Hurricane lamps account for 70 percent of the units sold, while the flashlights account for the remaining 30 percent of unit sales. The unit sales price of the lamps is $9.00, and the unit variable cost is $4.00. The unit sales price of the flashlights is $7.00, and the unit variable cost is $3.00.
<u>To calculate the weighted-average contribution margin, we need to calculate first the weighted-average selling price and weighted average variable cost for each product.</u>
weighted average selling price= (selling price* weighted sales participation)
weighted average selling price= (0.7*9 + 0.3*7)= $8.4
weighted average variable cost= (variable cost* weighted sales participation)
weighted average variable cost= (0.7*4 + 0.3*3)= 3.7
<u>Now, we can calculate the weighted average contribution margin:</u>
weighted-average contribution margin= 8.4 - 3.7= $4.7
