Firlakuza [10]

selling goods only at certain predetermined prices that reflect definite price breaks is called Price lining

Price lining, also known as product line pricing, is a marketing tactic where a company charges for its products in accordance with its quality, features, or other characteristics to set them apart from competing ones.

Price line, to put it simply, is the practice of placing comparable products in various price ranges, each of which differs significantly in terms of the characteristics or qualities it offers. These brackets typically have lower starting prices and higher price points.

Despite having "price" in its name, price lining is a marketing tactic. The major goal of this strategy is to increase sales and audience size by making the offering more appealing to a wider range of consumers.

Apple, a company that makes smartphones, is a good illustration of price lining in action. Apple offers its iPhone lineup in a range of price points, with each model differing mainly in the small number of extra features that are added to the more expensive ones. Instead of solely selling expensive iPhones, Apple now offers a variety of models to appeal to customers with varying levels of purchasing power, which helps them grow sales.

a. Sales price variance             $104,000            ($110,000)      ($6,000) U

b. Activity variance                   $160,000           $420,000     $580,000 F

c. Mix variance                           $85,000           $180,000     $265,000 F

d. Quantity variance                $189,000             $70,000     $259,000 F

Explanation:

a) Data and Calculations:

                                                      Partner                 Staff

Budgeted billable rate per hour   $800                    $210    

Budgeted variable cost per hour    375                      120

Budgeted billable hours              5,000                20,000

Budgeted revenue             $4,000,000        $4,200,000

Budgeted variable cost         1,875,000          2,400,000

Actual revenue                  $4,264,000         $4,510,000

Actual billable hours                   5,200                22,000

Actual billable rate per hour       $820                   $205

Budgeted billable rate per hour $800                    $210

Variance in price                           $20                       ($5)

Sales price variance            $104,000            ($110,000)      ($6,000)

Sales price variance = (Standard price - Actual price) * Actual billable hours

= ($800 - $820) * 5,200 + ($210 - $205) * 22,000

= $20 * 5,200 + ($5) * 22,000

= $104,000 - 110,000

= $6,000 U

Activity variance = (Actual billable hours - Standard billable hours) * Standard rate

= (5,200 - 5,000) * $800 + (22,000 - 20,000) * $210

= (200 * $800) + (2,000 * 210)

= $160,000 + 420,000

= $580,000 F

                                                  Partner                 Staff        Total

Budgeted revenue             $4,000,000        $4,200,000   $8,200,000

Budgeted variable cost         1,875,000          2,400,000      4,275,000

Budgeted contribution       $2,125,000         $1,800,000   $3,925,000

Actual revenue                  $4,264,000         $4,510,000   $8,774,000

Actual variable cost              1,950,000          2,640,000    4,590,000

Actual contribution             $2,314,000         $1,870,000   $4,184,000

Quantity variance                 $189,000              $70,000     $259,000

Quantity variance = Budgeted contribution - Actual contribution

= $3,925,000 - $4,184,000

= $259,000 F

Mix Variance:

Standard contribution margin  $425                  $90

Volume variance                         200                2,000

Mix variance =                     $85,000           $180,000
