Hi, Austin,
This is a word problem in which you can set up a system of equations. Let x = the salary for state A and y = the salary for state B. It states that the total of their salaries is 308,545, so this simply means you have to add the two salaries, so you can write: x + y = 308,545. Also, the problem mentions that state A earns 50,815 more than that of state B, so you can say state A = state B + 50,815, or, in terms of variables, x = y + 50,815. So your two equations are:
x+ y = 308,545 and x = y + 50,815
You can use a substitution method by plugging what x is from the right equation into the left equation.
x + y = 308,545 becomes (y+50,815) + y = 308,545
Combining like terms gives you
2y + 50,815= 308,545
Subtracting 50,815 on both sides (to solve for y) gives you:
2y + 50,815-50,815= 308,545-50,815
2y = 257,730
Now, you must divide both sides by 2 in order to solve for y:
2y/2= 257,730/2
y = $128,865; so this is the salary of the government of state B
Now we can plug this value into x = y + 50,815 to get x:
x = y + 50,815 = 128,865+50,815 = $179,680; this is the salary of the government of state A
That is all there is to it :)
