Is there any errors in it that makes my test cases to fail?

Question

a = input().split(" ")
b = {'Nachos':'6.00','Pizza':'6.00','Cheeseburger':'10','meal':'10','Water':'4.00'}
r = 0
for i in a:
g = b.get(i,'5.00')
r = r+float(g)
print(r+1.75)
You and three friends go to a baseball game and you offer to go to the concession stand for everyone. They each order one thing, and you do as well. Nachos and Pizza both cost $6.00. A Cheeseburger meal costs $10. Water is $4.00 and Coke is $5.00. Tax is 7%.

Task
Determine the total cost of ordering four items from the concession stand. If one of your friend’s orders something that isn't on the menu, you will order a Coke for them instead.

Input Format
You are given a string of the four items that you've been asked to order that are separated by spaces.

Output Format
You will output a number of the total cost of the food and drinks.

Sample Input
'Pizza Cheeseburger Water Popcorn'

Sample Output
26.75

Explanation
Because Popcorn is not on the menu, this friend gets a coke which brings the subtotal to $25.00 and $26.75 with tax.

Answer 1

a = input().split(" ")
b = {'Nachos':'6.00','Pizza':'6.00','Cheeseburger':'10','Meal':'10','Water':'4.00'}
r = 0
for i in a:
g = b.get(i,'5.00')
r = r+float(g)
print(r+(7/100))
Is it correct now??

Answer 2

Sorry I forgot!

Answer 3

a = input().split(" ")
