Question 1144147: We have three pay levels. Level 1 employees begin at $15,000. The notes say that in the third year the salary should rise to $19,000. Level 2 employees start at $30,000 and according to the notes, their salary should rise to $36,000 in year 3. Finally, Level 3 employees start at $50,000 and the notes say that they should be making $58,000 by the end of year 3. The only other piece of information I have is that the growth of salary over time is supposed to follow a linear growth pattern - whatever that means.
The notes also say that once a Level 1 employee has worked long enough to reach a salary of $30,000 he or she should either be promoted to Level 2 or fired. The same applies to Level 2 employees when they reach $50,000 in salary. Can you help me out? I need first to know what exactly is the rate of increase for each level of employee over time. I would also like a mathematical model that will allow me to input the number of years the employee has been working for us and give back their current salary.
Finally, I would like to know after how many years of working for us a Level 1 employee should expect to be promoted to Level 2 and after how many years of working for us can a Level 2 employee be promoted to a Level 3.

Question 1145192: The problem asks to find any intercepts and graph:
0.1x-0.2y=0.4
The answer is y-int (0,-2) and x-int (4,0). How do you get that x-int????
My work:
.1x-.2y=.4
Subtract .1x from both sides -.2y= -.1x+.4
Divide -.2 from both sides y=.1/.2x-.4/.2
Y=1/2x-2
X-int (-1,2) and y-int (0, -2)
