Code Problem 4 in Python 2.
Problem 4
You’ve been hired to write a Python program for scanned items at a grocery mart. The scan is of the form [x, y, z] where x is the number of items purchased, y is the price of the item, and z is whether the item is taxable (7% tax on grocery items). For example assume you were given the list below:
[[1, 1.45, 1], [3, 4.24, 1], [2, 14.00, 0], [4, 1.25, 1]]
This means the amount owed is:
amt = 1(1.45) (1.07) + 3(4.24) (1.07) +2(14.00) + 4(1.25) (1.07)
= ((1.45 + 12.72 + 5.00)1.07) + 28.00
= 19.17(1.07) + 28.00
= 20.51 + 28.00
= 48.51
Code the problem in Python 2 and add “comments explaining what the code is doing.
