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:

$450 + 0.20x \ge 35y$

We make use of the following representation:

$x \to$ weekly sales from cars.

$y \to$ hours worked in a week

His weekly salary is then calculated as:

Salary (S) = Earnings per week + Commission * Sales from car

So, we have:

$S = 450 + 20\% * x$

Express percentage as decimal

$S = 450 + 0.20* x$

$S = 450 + 0.20x$

Assume he works for y hours in a week.

His hourly rate is:

$Hourly = \frac{S}{y}$ --- i.e. weekly salary divided by number of hours

$Hourly = \frac{450 + 0.20x}{y}$

For this rate to be at least $\$35$ , the following condition must be true

$Hourly \ge 35$ --- i.e. is hourly rate must be greater than or equal 35

So, we have:

$\frac{450 + 0.20x}{y} \ge 35$

Multiply both sides by y

$450 + 0.20x \ge 35y$

Which of the graphs best represents a system of equations that has no solution?

Lesechka [4]

When the lines are parallel then there is no solution to the system of equations.
This happens because the intersection is the solution. And when there is no intersection then there is no solution.
