Answer:
too much reading, can you put more points.
(edit: OML SO SORRY -THOUGHT THIS WAS QUESTIONS)
Step-by-step explanation:
Let x= number of board games
<span>20x=10410+2.65x </span>
<span>-2.65 -2.65 </span>
<span>17.35x=10410 </span>
<span>/17.35 /17.35 </span>
<span>x=600 </span>
<span>You would need to sell at least 600 board games to break even</span>
Answer:
0 < t < 
After 1.67 days the stocks would be sold out.
Step-by-step explanation:
The price of a certain computer stock after t days is modeled by
p(t) = 100 + 20t - 6t²
Now we will take the derivative of the given function and equate it to zero to find the critical points,
p'(t) = 20 - 12t = 0
t = 
t =
days
Therefore, there are two intervals in which the given function is defined
(0,
) and (
, ∞)
For the interval (0,
),
p'(1) = 20 - 12(1) = 20
For the interval (
, ∞),
p'(2) = 20 - 12(2) = -4
Positive value of p'(t) in the interval (0,
) indicates that the function is increasing.
0 < t < 
Since at the point t = 1.67 days curve is showing the maximum, so the stocks should be sold after 1.67 days.
