Answer:

  • 30 baloons per hour

Step-by-step explanation:

Use some points on the graph:

  • (0, 0), (2, 60), (4, 120), (8, 240)

The graph is a line passing through the origin, so this is a proportional relationship.

Standard form of such relationship is

  • y = kx, where k- coefficient of proportionality

Using one of the coordinate pairs find the value of k

  • 60 = 2k
  • k = 60/2
  • k = 30

This is indicating the number of baloons filled per hour is 30.
