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
Wdym? Can you insert a photo or something.. I’m confuse uh..
First you would subtract 30 from both sides
they divide each side by 5 to get -7
y =-7
Each person will get a full brownie leaving you left over with 2 full brownies. You can cut both of the remaining brownies into 3rds giving you 6 pieces. Each person can then get 2 prices. This is 1 and 2/3 brownies per person
