Answer:x=q(2s-q)/2
Explanation:
x+o.5q^2=sq
x * 10+0.5q^2 * 10=sq * 10
10x+5q^2=sq * 10
10x+5q^2-5q^2=sq * 10-5q^2
10x=sq *10-5q^2
10x/10=sq * 10/10-5q^2/10
x=10sq-5q^2/10
x=5q(2s-q)/2
x=q(2s-q)/2
This * represents multiplication and x represents s(q).
Sorry, we havent done finding the equilibrium price in class, so i just show'd you finding the value.
