The expression is 100x + 50y ≤ 800.
Explanation:
The hip hop DJ charge for $100 per hour. Let x be number of hours of hip hop :

For rap DJ, the charge is $50 per hour. Let y be the number of hours of rap :
![rap = 50 * y](https://img.qammunity.org/2021/formulas/mathematics/college/mzxw4moholw6pp6b6j06qy5z5y9v1kejlj.png)
![rap = 50y](https://img.qammunity.org/2021/formulas/mathematics/college/qhjrh3zu8tospulitmln0ioxqa0480i951.png)
Given that both DJs spend a maximum of $800. So the final expression is :
![100x + 50y \leqslant 800](https://img.qammunity.org/2021/formulas/mathematics/college/djxa4dys46r3y5mnjx8qb8eu1z3plnq5gh.png)
