Write a single statement that assigns totalCost with the discounted cost of item 1 and item 2 . Use the provided function DiscountedPrice to determine the discounted cost of each item: function saleitemcost = DiscountedPrice(originalitemcost, discountedRate) \% originalitemcost: Original cost of an item in dollars % discountedRate: Discount rate as a decimal value saleitemcost = originalitemcost * (1 - discountedRate); end Ex: If item 1 costs 10 and has a 0.5 discount rate, and item 2 costs 20 and has a 0.4 discount rate, then assign totalCost with 17 (ex: DiscountedPrice (10,0.5)+ DiscountedPrice (20,0.4) is equal to 5+12)
