My code runs in workspaces but doesnt pass the challenge.

from operator import add
from functools import reduce


prices = [
    (6.99, 5),
    (2.94, 15),
    (156.99, 2),
    (99.99, 4),
    (1.82, 102)
]

def product_sales(tuple):
  a,b = tuple
  return a*b



total = reduce(add, map(product_sales, prices))

the challenge is asking the I find the per-product totals and then add all those puppies up recursivly

prices.py
from operator import add
from functools import reduce


prices = [
    (6.99, 5),
    (2.94, 15),
    (156.99, 2),
    (99.99, 4),
    (1.82, 102)
]

def product_sales(tuple):
  a,b = tuple
  return a*b



total = reduce(add, map(product_sales, prices))

Hey David. I tried copying and pasting the second code set you posted and it passed all the tests for the challenge. I would recommend giving the challenge another try and double checking that there aren't any inadvertent syntax errors happening when copying from work spaces. Hope this helps!
