Answer: Graph A
Explanation:
I got the answer by looking at the lines origins, because the daily income starts out at $10 a day. This took out B and D for answers since they start at (0,0) not (0,10)
Then I found the value of 10x.5 for each newspaper, graph c's slope was to steep to represent that, thus making it Graph A.
In conclusion the correct answer is graph A
