I got my answer 17/.. but they want it as a whole number. any ideas what i might have done wrong?

17/2*

yes i did it exactly like that

and the max occured at 17/2?

then i multiplied them out and to maximize I found the derivative.

well i got f(x)= -3x^2/4+51x/4+2601

and f '(x)= -6x/4+51/4

i set that to zero and got 17/2

by yield, i mean total yield, not yield per tree.

x = 8 => 2655 peaches
x = 9 => 2655 peaches

i tried those also

it says wrong

did you try 8?

yeah

:/

woahhhh how is it 59?

its saying correct to that one

did you use the second derivative test? or something?

51 + 8 = 59. there were 51 already planted plus the 8 you added to maximize the total yield.

but if it's 8.5 shouldnt we round it to 9?

so wouldnt it be 60?

ok...

maybe 60 would also work (as an answer) but it's not as practical as 59.

im a little confused on that.

yeah i tried 60 but it kept saying wrong.

i mean mathematically speaking best round is 60 and then adding it to the already planted trees

meaning 51+ 9....

huh?

how old are you?

this example sounds scary.

yeah, intentionally.

i understand you, but i just don't like the example.lol

thanks anyways, i see the problem clearly now.

lol, sorry. it's just what popped out of my head.

thanks again!

excellent. ask your teacher to be more explicit in what is wanted next time.
you're welcome!
