Final answer:
To find the number of oranges the trader bought, we first need to determine the selling price per orange. Since she sold the oranges at 8 cents each and made a profit of $4.50, the cost price per orange can be calculated using the equation: Cost price per orange + Profit per orange = Selling price per orange.
Step-by-step explanation:
To find the number of oranges the trader bought, we first need to determine the selling price per orange. Since she sold the oranges at 8 cents each and made a profit of $4.50, the cost price per orange can be calculated using the equation:
Cost price per orange + Profit per orange = Selling price per orange
Let x be the cost price per orange. We have:
x + $4.50 = $0.08
Subtracting $4.50 from both sides, we get:
x = $0.08 - $4.50 = -$4.42
The cost price per orange comes out to be a negative value, which is not possible. Therefore, there is an error in the question or the information given.
