Question 89520This question is from textbook algebra
: I am asked to find the equilibrium for demand and supply equations
d=-5p+40
S=-p^2+30p-8
so far I have
-p^2+30p-8=-5+40
0=p^2-30p+48
so,
p=35+ sq rt(-35)^2-4(48)/2
=35+ sqrt701/2

I am asked to find the equilibrium for demand and supply equations
d=-5p+40
S=-p^2+30p-8
so far I have
-p^2+30p-8=-5p+40
0=p^2-35p+48
so,
p = [35+- sqrt((-35)^2-4(48)]/2
p = [35+-sqrt(1033)]/2
p = $33.57 o $1.43
