U=v+ 2t=
U/2t = r+2t/2t
=U/2t=r OR. r= U/2t
Answer:
-1.39
Step-by-step explanation:
Revenue and cost as a function of units sold are
and
respectively.
we are have to know for which value or input units are these functions at maximum which translates to for how many units is the revenue maximum and for how many same units is our cost minimum.
The solutions are (2.1925, 5.1925) and (-3.1925, -0.1925)
<em><u>Solution:</u></em>
Given that,

<em><u>We have to substitute eqn 1 in eqn 2</u></em>






Substitute x = 2.1925 in eqn 1
y = 2.1925 + 3
y = 5.1925
Substitute x = -3.1925 in eqn 1
y = -3.1925 + 3
y = -0.1925
Thus the solutions are (2.1925, 5.1925) and (-3.1925, -0.1925)
