So let's say he was earring x before his raise. That means that:
x times 1.09 = 654 (1.09 represents 100% (this is the 1.0) of his original salary plus 9% (this is the .09) his raise.
So,
1.09x = 654; now divide both sides by 1.09 to isolate and solve for x, and you get x = $600.
If i remember correctly.. it’s C, you cant have the X values repeating.
Answer:
you would need to give the figure
10x + 19y = -11
19y = -10x - 11
y = -10/19x - 11/19 <===
The correct answer would be 3.65.
