![24x+10y\geq 200](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mv1j1qtagct3i7w23zhnerwhyxmwftdfoc.png)
Explanation:
Givens:
- Phillip needs at least 200 roses.
- There will be 24 roses per centerpiece.
- There will be 10 roses per bouquet.
represent the number centerpieces, and
represents the number of bouquets.
According to the problem, we can define the number of roses per a centerpiece:
![24x](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4qssaeoolv3a54685qxo4gt5esrnx3877x.png)
The number of roses per bouquet:
![10y](https://img.qammunity.org/2020/formulas/mathematics/middle-school/azaal0fmm829p4kor8vzh1rgadqq92lz1y.png)
So, the problem restricts the amount of roses, at least 200, that means, 200 or more than 200 roses. Therefore the expression that represent the amount of roses would be:
![24x+10y\geq 200](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mv1j1qtagct3i7w23zhnerwhyxmwftdfoc.png)
As you can observe, the inequality includes the 200 roses restriction, and the amount of roses per centerpieces and per bouquet.
