A fictional country has 3 denominations of money: gold, silver and copper coins.
1 gold coin = 20 silver coins
1 silver coin = 4 copper coins
,Given a total number of copper coins (given in the variable copper), we want the
computer to tell us how many gold coins (gold), silver coins (silver) and copper coins
(copper) are needed to make change while minimizing the number of coins.
Incomplete code is given below. Choose the option below that correctly completes
the code segments marked A and B.
copper = 1000 # or any other positive integer
gold = copper // A
copper = copper % A
silver = copper // B
copper = copper % B
Question 10 options:
Replace A with 80, replace B with 20.
Replace A with 80, replace B with 4.
Replace A with 4, replace B with 20.
None of these is correct.
Replace A with 20, replace B with 4.

We want to write the function buy(num_pizzas, pizza_cost, budget) which returns how
much money we have leftover after buying some pizzas. The maximum number of
pizzas we might buy is num_pizzas, the cost of a single pizza is pizza_cost, and the
starting amount of money is budget. We can buy only whole pizzas, not fractions or
portions of a pizza. We will buy as many pizzas as we can, up to the limit num_pizzas.
