Freelancer Rates

Story

In this exercise you'll be writing code to help a freelancer communicate with a project manager by providing a few utilities to quickly calculate day- and month rates, optionally with a given discount.

We first establish a few rules between the freelancer and the project manager:

  • The daily rate is 8 times the hourly rate;
  • A month has 22 billable days.

The freelancer is offering to apply a discount if the project manager chooses to let the freelancer bill per month, which can come in handy if there is a certain budget the project manager has to work with.

Discounts are modeled as fractional numbers followed by a % (percentage) between 0.0% (no discount) and 90.0% (maximum discount).

Tasks

These are example tasks that fit the story of the freelancer communicating with a project manager:

  • Calculate the day rate given an hourly rate
  • Calculate the month rate, given an hourly rate and a discount
  • Calculate the number of workdays given a budget, rate and discount

Terminology

These are recommendations, not rules, for recurring terminology in the instructions (including stub commentary)

  • Daily rate is 8 times the hourly rate; it should be mentioned
  • Monthly rate is 22 times the daily rate; it should be mentioned
  • If discount is supplied as a different type than the numeric types, use the terminology discounts are modeled as
