How to find the equations
Assuming
- the number of regular hot dogs sold is x and
- the number of hot dog supremes sold is y
The number of regular hot dogs sold x must be between 30 and 75.
30 ≤ x ≤ 75
The number of hot dog supremes sold (y) must be between 15 and 45.
15 ≤ y ≤ 45
The total number of sales must not exceed 100.
x + y ≤ 100
