Answer:
The amount of sales in order to cover his monthly expenses must be greater than or equal to $22,500
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
so
The inequality that represent this situation is
![0.12x+2,700\geq 5,400](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ti0smiyvc78sudj2ezvro0gfmrddbs0kov.png)
solve for x
subtract 2,700 both sides
![0.12x \geq 5,400-2,700](https://img.qammunity.org/2021/formulas/mathematics/middle-school/56jmo9tjveryih5y3ecx13l9q5kyskkygf.png)
![0.12x \geq 2,700](https://img.qammunity.org/2021/formulas/mathematics/middle-school/u7mpgtpgq0oc9d3hxt3c3i4j79klaa18x8.png)
divide by 0.12 both sides
![x \geq \$22,500](https://img.qammunity.org/2021/formulas/mathematics/middle-school/13qjgdpskzczrchymv4p2mosr18ig17bgj.png)
