A gas station sells gallons of gasoline per year, which is delivered times per year in equal shipments of gallons. The cost of each delivery is dollars and the yearly storage costs are , where is the length of time (a fraction of a year) between shipments and is a constant. Which value of minimize the costs? Hint: Express in terms of .

168

step-by-step explanation:

i am pretty sure that the answer is 168

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
