The cost of a customer's electricity bill is based on the number of units of electricity the customer uses. - For the first 25 units of electricity.the cost is 5 per unit. - For units of electricity after the first 25, the cost is 7 per unit. Which of the following code segments correctly sets the value of the variable cost to the cost, in dollars. of using numunits units of electricity?

To determine the correct code segment that sets the value of the variable `cost` to the cost of using `numunits` units of electricity, we need to consider the pricing structure provided:- For the first 25 units, the cost is 7 per unit.Let's break down the cost calculation based on the number of units used:1. If `numunits` is less than or equal to 25, the cost is simply `numunits * 5`.2. If `numunits` is greater than 25, the cost is calculated as follows: - The cost for the first 25 units is `25 * 5`. - The cost for the remaining units (i.e., `numunits - 25`) is `(numunits - 25) * 7`.Now, let's write the code segment that correctly calculates the cost based on these rules:```pythonif numunits <= 25: cost = numunits * 5else: cost = (25 * 5) + ((numunits - 25) * 7)```This code segment checks if `numunits` is less than or equal to 25. If it is, it sets `cost` to `numunits * 5`. Otherwise, it sets `cost` to the sum of the cost for the first 25 units and the cost for the remaining units.Here is the complete code segment in Python:```pythonnumunits = 30 # Example value for numunitsif numunits <= 25: cost = numunits * 5else: cost = (25 * 5) + ((numunits - 25) * 7)print("The cost is:", cost)```This code will correctly calculate the cost based on the given pricing structure.
