Answer:
Income will increase by $20,000.
Step-by-step explanation:
First, we need to calculate the current income:
Current income= 4,000*(50 - 10) - 15,000= $145,000
Now, the new selling price, fixed costs, and sales in units:
Selling price= 50*0.9= $45
Fixed costs= $45,000
Sales= 4,000*1.5= 6,000
New income= 6,000*(45 - 10) - 45,000= $165,000
Difference= 165,000 - 145,000= 20,000
Income will increase by $20,000.
