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.
