Re: Help with a homework assignment: profit equation  TOPIC_SOLVED

Hi Buddy, Thanks for the replies My answer for the reasonable part is that it is not reasonable, because the more products you make, the more your profit decreases. With volume your profit should increase, not decrease. 40 items equal $5865, 50 items equals $5667 . I will work on your other suggesti...

Re: Help with a homework assignment: profit equation  TOPIC_SOLVED

i don't know what you mean by "convert the numbers to standard equation". try plugging this into the quadratic formula. then pick "reasonable" rounded answers (like "i can't make 2.65 units, but I can 2 or 3 units" kind of thing) This is what I have for 4 although I do...

Re: Help with a homework assignment: profit equation  TOPIC_SOLVED

So is the below correct? How do you work with the decimal portion? (The forum doesn't allow me to use the square root symbol or the squared symbol without a sql database error, so I had to use a V and a ^2 instead) 0 = -3.2(x)^2 + 268.2(x) -5166 a = 3.2 b = 268.2 c = -5166 __________________________...

Re: Help with a homework assignment: profit equation  TOPIC_SOLVED

I just had an epiphany. Can I simplify the problem more than this? 0 = -3.2(x)^2 + 268.2(x) -5166 0 = (-3.2(x)^2 + 268.2(x) -5166) 10 or 0 = 32x^2 + 2682 - 51660 a = 32 b = 2682 c = -51660 ____________________________________________ x = -2682 ± V(2682)^2 - 4(32)(-51660) ----------------------------...
