Final answer:
To make a profit of $1600, you need to sell approximately 457 widgets in a month.
Step-by-step explanation:
To calculate the number of widgets needed to be sold in a month to make a profit of $1600, we need to consider the costs and revenues associated with selling widgets.
The fixed costs of the business are $860 for rent each month, regardless of the number of widgets sold. The variable cost per widget is $3.22.
Let's assume x is the number of widgets sold.
To calculate the profit, we need to subtract the total costs from the total revenues:
Profit = (Revenue per widget * x) - (Fixed costs + Variable costs per widget * x)
Since we want the profit to be $1600, we can set up the equation:
1600 = (8.59 * x) - (860 + 3.22 * x)
Simplifying the equation:
1600 = 5.37x - 860
Adding 860 to both sides:
2460 = 5.37x
Dividing both sides by 5.37:
x ≈ 457
Therefore, you would need to sell approximately 457 widgets in a month to make a profit of $1600.
