Which equation best describes the graph? urgent!

B. The slope is positive since when x goes up so does y. Also, we can see it crosses the y axis at 3, which makes the number added at the end positive 3. 

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
