To solve the problem it is trial and error since we don’t know how many hotdogs and bottled water was sold. To trim down to problem, negative values and decimal values are not included because there is no negative amount and a decimal amount.

The equation is

4x + 2y > 12

At (0,6)

4 (0) + 2 (6) > 12

12 > 12 so it is wrong

At (2,1)

4 (2) + 2 (1) > 12

10 > 12 correct

At (1, 3)

4 (1) + 2 (3) > 12

10 > 12 correct

At (2,2)

4 (2) + 2 (2) > 12

12> 12 wrong
