Answer:
- y ≤ 70
- x + y ≤ 120
- 3.75x +6.25y ≥ 530
Step-by-step explanation:
You want inequalities using x and y for numbers of tacos and burritos, respectively, that represent ...
- the total of tacos and burritos cannot exceed 120
- revenue from tacos for 3.75 and burritos for 6.25 cannot be less than 530
- the number of burritos is at most 70.
Inequalities
We generally like to write the inequalities in the order the constraints are given in the problem statement. This helps ensure nothing is missed.
The first constraint is on the total number of products that can be produced:
x + y ≤ 120
The second constraint is on the required revenue:
3.75x +6.25y ≥ 530
The remaining constraint is on the possible numbers of burritos:
y ≤ 70
Your answer selections may require you to rearrange these inequalities.
Graph
The attached graph shows these inequalities. The solution space is the area that is shaded by all three inequalities. It is a flat-topped triangle.

Additional comment
For most problems of this nature, there are additional constraints that x ≥ 0 and y ≥ 0, which restricts the solution of each inequality to the first quadrant.
