You have just started a new stationary shop. Your profit-per-item depends on the total quantity of item sold. Hide Copy Code Your profit-per-item depends on the total quantity of item sold. The scheme shown below is used to determine the total profit: Quantity Profit-per-item 0–1000 $1 1001–5000 $2 5001 and above $5 Save Note that this is a graduated profit. The profit for selling up to 1000 items is $1, for next 4000 items is $2 and beyond that is $5. If the total quantity of item sold is 10000, the profit is 1000 * $1 + 4000 * $2 + 5000 * $5 = $34000. Your goal is to make $50,000 a year. Write a program that uses a do-while loop to find out the minimum quantity of item you have to sell in order to make $50,000
