Hi
Going throw an example about the fixed and variable costs (Engineering Economy page 25), the result x=17,121 cubic yd seems to be wrong. The result of the equation $53,160+$4.945=$8.05x should be 6,604 cubic yards.

The equation is ; $53,160+$4.945x=$8.05x
so :
$53,160 = $8.05x - $4.945x
$53,160 = $3.105x
finally
x = $53,160/$3.105 = $17,121
Jesus, I missed the X in the equation....confirmed...my brain is atrophied!!!
Thanks Yoyok
