You are currently in Grade 10 and in order to earn extra money you accept a job at a Spur restaurant as a waiter. You work the following shifts per month:
- Four Friday shifts per month for \(\text{5}\) hours. Friday rate/hour = \(\text{R}\,\text{20}\)
- Four Saturday shifts per month for \(\text{10}\) hours. Saturday rate/hour = \(\text{R}\,\text{30}\)
- Two Sunday shifts per month for \(\text{8}\) hours. Sunday rate/hour = \(\text{R}\,\text{40}\)
- Estimated tips earned per month = \(\text{1,5}\) \(\times\) your monthly salary.
Calculate your total income for one month.
Total Income earned = [(\(\text{4}\) \(\times\) \(\text{5}\)) \(\times\) \(\text{R}\,\text{20}\) + (\(\text{4}\) \(\times\) \(\text{10}\)) \(\times\) \(\text{R}\,\text{30}\) + (\(\text{2}\) \(\times\) \(\text{8}\)) \(\times\) \(\text{R}\,\text{40}\) ] = [\(\text{R}\,\text{400}\) + \(\text{R}\,\text{1 200}\) + \(\text{R}\,\text{640}\)] = \(\text{R}\,\text{2 240}\) / month
