Final answer:
The change in profitability for IM is -$41324.05.
Step-by-step explanation:
To compute the change in profitability, we need to calculate the change in sales revenue and subtract the change in costs. The change in sales revenue can be calculated by multiplying the change in quantity sold by the change in price. In this case, the change in quantity sold is the difference between the new and old quantity sold, which is 2243 - (2243 * (-0.67)) = 2243 * (1 + 0.67) = 3778.81 units. The change in price is $61 - $66 = -$5.
Therefore, the change in sales revenue is 3778.81 * -$5 = -$18894.05. Now, we need to calculate the change in costs. The unit cost is given as $20, so the change in costs is 2243 * ($20 - $5) = $22430. Finally, we can calculate the change in profitability by subtracting the change in costs from the change in sales revenue: -$18894.05 - $22430 = - $41324.05.
Therefore, the change in profitability for IM is -$41324.05.
