Answer:
The inequality that can be used to determine the number of guitar lessons Gale could take using her birthday money is:
![25x + 50 \leqslant 200](https://img.qammunity.org/2022/formulas/mathematics/high-school/bvi0rhvkbdsxggo5c7vv5ohcanwqahiztd.png)
The solution to the inequality is:
![x \leqslant 6](https://img.qammunity.org/2022/formulas/mathematics/high-school/15790uv0wa32f51kfj0ubi2h0jmvpzett0.png)
She can take at most, 6 guitar lessons
Explanation:
Total amount Gale received is $200
For rental equipment, she paid $50
Each guitar lesson will cost $25
Let x represent the number of lessons she could take, then the total amount she will spend must bot exceed $200
The guitar lesson will cost a total of 25x
So, her total spending will be:
![25x + 50](https://img.qammunity.org/2022/formulas/mathematics/high-school/palpy9v3c05ijnp7w0c5twpdzoej2ws71w.png)
This must be at most $200
![25x + 50 \leqslant 20](https://img.qammunity.org/2022/formulas/mathematics/high-school/fsww42rgpvhafb7nubdg9w5i1ig7119v64.png)
Solving the above inequality:
![25x \leqslant 200 - 50 = 150](https://img.qammunity.org/2022/formulas/mathematics/high-school/b8l0t1ju08h8tfxjnye2s2ar6zpm5k674d.png)
![x \leqslant (150)/(25) = 6](https://img.qammunity.org/2022/formulas/mathematics/high-school/zz3ddyzwwu2hnuzlgus2g1dk7lv1lxc1pl.png)
