x/60=((3950-x)/45)+8.1 Is the thing that is giving me problems.
x/60=((3950-x)/45)+8.1
Multiply through by the common denominator of 45, 60 = 180
So we have
3x = 4(3950 - x) + 1458 simplify
3x = 15800 - 4x + 1458 add 4x to both sides and simplify the right side
7x = 17528 divide both sides by 7
x ≈ 2465.43
Ok, I just wanted to make sure that I was doing the right thing that's all.
