So if we want to make sure y x 15 is less than 180, we can plug in low values and check the inequality.
If we plug in 0, we get 180 > 0 which is true.
If we plug in 1, we get 180 > 15 which is true.
If we plug in 2, we get 180 > 30 which is true.
Therefore, 3 values that satisfy the inequality are 0, 1, and 2.
