Tyler Corporation is a wholesaler that sells a single product. Management has provided the following cost data for two levels of monthly sales volume. The company sells the product for $127.20 per unit. Sales volume (units) 5,000 6,000 Cost of Sales $419,000 $502,800 Selling and Admintrative costs $186,000 $202,200 The best estimate of the total contribution margin when 5,300 units are sold is:

total contribution margin= $144,160

Explanation:

First, we need to calculate the unitary variable cost of sales:

Cost of sales= 419,000/5,000= $83.8

Cost of sales= 502,800/6,000= $83.8

It is all variable.

Now, to estimate the variable component of selling and administrative, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (202,200 - 186,000) / (6,000 - 5,000)

Variable cost per unit= $16.2

Finally, the total contribution margin:

total contribution margin= number of units*unitary contribution margin

total contribution margin= 5,300*(127.2 - 83.8 - 16.2)

total contribution margin= 5,300*27.2

total contribution margin= $144,160

administrative jobs normally have someone answering phone calls and scheduling appointments, filing patient or customer information, making sure the front of the office looks nice to those who enter the building. administrative jobs can also include making sure the manager has everything they need for meetings, making delivers and much more. administrative jobs are important to most businesses as are customer service focused as they are often one of the first impressions a consumer sees of a business.
