The answer is the first table: (0, 0), (10, 50), (51, 255), (400, 2000)
Our function is y = 5x
Let's check all of the tables:
Table 1:
x = 0, y = 0 ⇒ 0 = 5 · 0 ⇒ 0 = 0
x = 10, y = 50 ⇒ 50 = 5 · 10 ⇒ 50 = 50
x = 51, y = 255 ⇒ 255 = 5 · 51 ⇒ 255 = 255
x = 400, y = 2000 ⇒ 2000 = 5 · 400 ⇒ 2000 = 2000
Since all calculations from the first table are correct, we can conclude that the first table represents viable solutions. Also, if you check it out, the third table gives all correct calculations for the function y = 5x, however, its solutions cannot be viable because the number of sold tickets and collected money cannot be negative numbers
