Delaying functions

You have been tasked with adding up your company's costs for the last 2 weeks. Because you know that you will want to run this same computation in the future with many more weeks, you think it might be a good idea to write it in a way that can be parallelized.

The arrays of costs of items for the last two weeks are available as costs_week_1 and costs_week_2, and numpy has been imported as np.

Instructions

Import the delayed() function.
Delay the np.sum() function and use it to create delayed sums of costs_week_1 and costs_week_2.
Add the two sums together to create another delayed object of the total.
Compute and print this total.
