Serhud [2]

Answer:

A

Step-by-step explanation:

The graphs are attached.

First of all, the day proposal goes out, 25 people know, so the initial condition is y = 25 at x = 0.

Hence, graph would start at y = 25.

Looking at the graphs, we can eliminate B and D immediately because they start at 50.

Now, it says every day, this number (y) triples, so 1 day after, it would be:

25 * 3 = 75

So, the graph would show x = 1 and y = 75

We can eliminate "C" as it doesn't show 75 at x = 1.

And we look at A and it is correct.

So,

A is the graph of the situation represented.
