The correct answer is C. Ambassador
The American colonies of 1760, did many Americans consider themselves British? Did they consider themselves Englishmen, even if born in the colonies? Also, am I right in the impression that a resident of Massachusetts would be the least likely to identify as British? That they were the most independent minded, even in 1760?
Due to the increase in hourly wages that each employee receives each year increases every three years by $ 0.50, this means that the increase remains constant over a period of 3 years, therefore the function described by this scenario is:
y= {0.5 if x <3
{1 if 3 ≤ x <6
{1.5 if 6 ≤ x <9
{2 if 9 ≤ x <12
Therefore, the last graph correctly represents the salary increase for x <12.
