(a) If the company desires a profit of $140,000, it should charge $22 per hour. This is calculated by adding the desired profit to the variable costs, resulting in $20 + $140,000 = $160,000. Then, divide this amount by the total number of consulting hours (20,000) to get $22 per hour.
(b) The markup on variable costs if the desired profit is $160,000 is 25%. This is calculated by dividing the desired profit ($160,000) by the variable costs ($20) and then subtracting 1, resulting in (160,000/20) - 1 = 7.5. Multiply this amount by 100 to get the markup percentage (7.5 x 100 = 750%).
(c) If the desired profit is $160,000, the markup on variable costs to cover unassigned costs and desired profit is 33%. This is calculated by dividing the desired profit plus unassigned costs ($400,000 + $160,000 = $560,000) by the variable costs ($20) and then subtracting 1, resulting in (560,000/20) - 1 = 27.5. Multiply this amount by 100 to get the markup percentage (27.5 x 100 = 2750%).
