Python 3.0 via PyCharm

Purpose: To distinguish between the different parts of functions and function calls. Degree of Difficulty: Easy Below is a program that uses functions to compute the total cost, including tax, of a purchase of several blankets 1 def add tax (subtotal): 2 3 4 5 6 3 Adds 5% tax to the subtotal input subtotal is the amount before tax returns total the amount including tax totalsubtotal + 0.05* subtotal return total 9 10 def blanket total( number_of_blankets , price_per_blanket): 3 12 13 14 15 16 17 18 19 20 21|# compute the total for a customer who purchases 1 blanket at5 per blanket 22 customer 1 blanket-total (1 , 5) 23 24 # compute the total for a customer who purchases 3 blankets at $4 per blanket 25 customer2blanket_total (3,4) 26 27|# compute the total for a customer who purchases 5 blankets at $6 per blanket 28 customer3 = blanket-total (5,6) Computes the total amount due for the purchase of a number of blankets including 5% tax number_of_blankets is the number of blankets purchased price per.blanket is the price Tor each blanket returns the total for the customer 3 total_before_taxnumber_of_blankets * price_per_blanket return add_tax (total_before tax) Answer the following questions.
