Software: You are working at a retail company that sells different types of fruits - apple, orange, banana. You want to estimate the value for [p + k] where p represents the price in dollars and k is an integer representing how much more you have in stock (in hundreds). The cost C(x) to transport x items at a time is $46 million per unit. Find an expression to represent the total shipping cost, given that it costs $ 12000 to ship every item from your warehouse to the buyer for every x number of units (a natural number). Note: You can assume that p and k are both integers with values between 1 and 15. Your answer must be less than or equal to 2960, and it should not include the cost of storing the items at your warehouse before they're shipped.
