We have a bunch of prices and sales numbers and we need to find out our total earnings.
Let's start by writing a function named product_sales that takes a single two-member tuple made up of a price and a number of units sold. product_sales should return the product of the price and the number of units.

prices = [ (6.99, 5), (2.94, 15), (156.99, 2), (99.99, 4), (1.82, 102) ] def product_sales((price, unit)): price, unit = passed_tuple

Hi! Let me break this down.
- Let's start by writing a function named product_sales - check! This is correct
- that takes a single two-member tuple - you should have a single argument in your function, right now you have two inside of a set of extra parentheses
- made up of a price and a number of units sold. - the tuple that is going to be passed in will be made up of these two values
- product_sales should return the product of the price and the number of units. - you should return the product (*) of the two values that are inside of the tuple
def product_sales(passed_tuple): price, units = passed_tuple return price * units
I hope this helps!
