    def total_cost(self):
        #vanilla ice cream is sold at a discount of half off!
        if self.flavor == "vanilla":
            total_cost = self.numScoops * .5*self.costPerScoop

        else:
            total_cost = self.numScoops * self.costPerScoop

        return total_cost

The answer is 4.0

The number of scoops is 4 and it costs 2 dollars per scoop. Since vanilla is the flavor and vanilla is half off, the total cost of this order is .5(4 * 2) = 4.0

Run the code to verify.
