If the company reduced price by 5% and got a 10% increase in sales volume, what would be the expected net profit?

Given the following:

Accounts receivable (starting) $800,000 Advertising $1,000,000 Cost of good sold $9,200,000 Depreciation expense $440,000 Insurance $200,000 Interest $420,000 Inventory (starting) $2,600,000 Labor expense $1,200,000 Loan principal payments $600,000 Management compensation $800,000 Miscellaneous expense $600,000 Owner's equity $4,000,000 Purchases of inventory $9,000,000 Receipts on accounts receivable $11,800,000 Rent $800,000 Sales (cash) $4,000,000 Sales (credit) $12,000,000 Utilities $240,000

I don't know how to get the 480,000 units in the following operation and the sale price:

we need to first calculate the new revenue and new costs.

New revenue:

New revenue = New sales volume * New sales price

The new sales volume is 10% higher than the current sales volume, so it is 480,000 units x 1.1 = 528,000 units

The new sales price is 5% lower than the current sales price, so it is $5.99 x 0.95=5.71 per unit

Therefore, the new revenue is 528,000 units x $5.71= $3,002,880
