Answer:

The amount of sales in order to cover his monthly expenses must be greater than or equal to $22,500

Step-by-step explanation:

Let

x----> represent the amount of sales Ollie will need

we know that

The amount of sales for the month multiplied by the commission rate as a decimal plus the fixed amount must be greater than or equal to $5,400 each month

The inequality that represent this situation is

$0.12x+2,700\geq 5,400$

solve for x

subtract 2,700 both sides

$0.12x \geq 5,400-2,700$

$0.12x \geq 2,700$

divide by 0.12 both sides

$x \geq \$22,500$

The amount of sales in order to cover his monthly expenses must be greater than or equal to $22,500
