Solution :
The cost of variable manufacturing is given as = $ 89,200
Number of units = 8000 units.
Therefore, the cost of variable manufacturing per unit
![$=(89,200)/(8000)$](https://img.qammunity.org/2022/formulas/business/college/ct60zkqt3eyqbdmq8liloab7sdxryniydv.png)

Therefore for 2000 units = 2000 x 11.15
= $ 22,300
Amounts in $
Sales 30,400 (2000 x 15.20)
Less : variable manufacturing cost 22,300
Less : fixed manufacturing cost 1,680
Less : variable selling and administrative cost 3800
Profit 2620
Therefore the profit is increased by $ 2620.
