The complete question implies that we define an inequality that represents the relationship between the number of hours worked in a week and the weekly sales
The inequality that relates the number of hours to the weekly sales is:
We make use of the following representation:
weekly sales from cars.
hours worked in a week
His weekly salary is then calculated as:
Salary (S) = Earnings per week + Commission * Sales from car
So, we have:
Express percentage as decimal
Assume he works for y hours in a week.
His hourly rate is:
--- i.e. weekly salary divided by number of hours
For this rate to be at least , the following condition must be true
--- i.e. is hourly rate must be greater than or equal 35
So, we have:
Multiply both sides by y
