Joan made a graph modeling her income and costs for selling x loaves of zucchini bread at the farmers' market.

After examining the graph, Joan determines that she will need to sell 19 loaves of bread in order to break even. Her coworker says that she is not correct, and that Joan actually only needs to sell 18.824 loaves of bread

Is Joan's answer practical in this situation, and why or why not?

A.
Joan's answer is not practical in this situation since the graph intersects below the x-value of 19.
B.
Joan's answer is not practical in this situation since income and costs can be measured in decimal increments.
C.
Joan's answer is practical in this situation since, based on the graph, there is no reason to report a value other than 19 loaves of bread.
D.
Joan's answer is practical in this situation since her costs are more than her income until she sells more than 19 loaves of bread.
