You own a coffee shop where you can buy bagels from a vendor for $1.45 each and sell them for $1.85 each. Unsold bagels are discarded. Over the past 10 days, you purchased 40 bagels each day and sold 40 bagels for 4 days and 30 bagels for 6 days. Calculate the potential profit to be made if you order 40 bagels, but only sell 30.
