Zara inflated more balloons after 2 minutes.

They both inflated the same number of balloons after 2 minutes.

Emily inflated more balloons after 2 minutes.

Answer 1

To determine who inflated more balloons after 2 minutes, we need to evaluate both Emily's performance (from the graph) and Zara's performance (from the table).

Let's look at Zara's balloon inflation:

According to the table:

• After 1 minute, Zara inflated 2 balloons.
• After 2 minutes, Zara inflated 4 balloons.

Now, looking at Emily's graph, we can see at 2 minutes (assuming we interpret the graph correctly):

• After 2 minutes, Emily inflated 8 balloons.

Now we can compare:

• Emily inflated 8 balloons after 2 minutes.
• Zara inflated 4 balloons after 2 minutes.

Thus, Emily inflated more balloons after 2 minutes.
