#read quantity from user
quantity=int(input("Enter the quantity of the product you want to purchase: "))
#variables
discount=0
amount=0
#check for 10-19 and assign discount
if(quantity>=10 and quantity<20):
discount=0.10
#check for 20-49 and assign discount
elif(quantity>=20 and quantity<50):
discount=0.20
#check for 50-99 and assign discount
elif(quantity>=50 and quantity<100):
discount=0.30
#check for 100 or more and assign discount
elif(quantity>=100):
discount=0.40
#calculate discount amount
discount=discount*quantity*100
#calculate amount
amount=quantity*100-discount
#print discount and total amount
print("Discount Amount: $",round(discount,2))
print("Total Purchase Amount: $",round(amount,2))

if quantity between 10-19 assign discount of 10% (0.1)
else if quantity between 20-49 assign discount of 20% (0.2)
else if quantity between 50-99 assign discount of 30% (0.3)
else if quantity 100 or more assign discount of 40% (0.4)
calculate discount as discount*quantity*100
calculate amount as quantity*100-discount
