Answer:
3rd option
Step-by-step explanation:
Answer:
g=6
Step-by-step explanation:
g=4 and g=5 will be more than 7 but g=6 is less.
Equilibrium is point where supply = demand
Solve with substitution.
From supply equation ---> q = 2p - 63
Sub into demand equation ---> (p+30)(2p-63+25) = 2584
Solve for p:
2p^2 +22p - 1140 = 2584
p^2 + 11p -1862 = 0
(p+49)(p-38) = 0
p = 38
Sub back into supply equation to find q
q = 2(38) - 63
q = 13
Answer: Equilibrium is 13 units sold at price of $38.
Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
