#Create a solution that accepts a string input representing a 
#grocery store item and an integer input identifying the number of items purchased on a recent visit. 
#The following dictionary purchase lists available items as the key and the cost per item as the value.

#purchase = {"bananas": 1.85, "steak": 19.99, "cookies": 4.52, "celery": 2.81, "milk": 4.34}

#Additionally,

#If fewer than 10 items are purchased, the price is the full cost per item.
#If between 10 and 20 items (inclusive) are purchased, the purchase gets a 5% discount.
#If 21 or more items are purchased, the purchase gets a 10% discount.
#Output the chosen item and the total purchase cost to two decimal places.

#REMEMBER ITS WANTING MATH NOT OUTPUTS FOR DISCOUNTS
