The acme-service is a simple service that provides a REST API to manage a list of products. The service is written in Elixir, uses the Phoenix framework, and a Postgres database. In this challenge, you will be asked to add a new feature to the service. The new feature is an endpoint that computes the total inventory cost of a product. The total inventory cost should be calculated by simply multiplying the prodcut's unit cost by the quantity. Below is a sample of the expected request/response.
GET /products/:id/total_inventory_cost
{
"data": {
"id": 1,
"category": "some category",
"unit_cost": 20,
"description": "some description",
"name": "some name",
"quantity": 10,
"total_inventory_cost": 200
}
}
The test below should pass when the feature is implemented correctly.

To start your Phoenix server:
- Install dependencies with
mix deps.get - Create and migrate your database with
mix ecto.setup - Start Phoenix endpoint with
mix phx.serveror inside IEx withiex -S mix phx.server
Now you can visit localhost:4000 from your browser.
