Suppose the supply and demand for a certain textbook are given by ​supply: p equals one half q squared comma ​demand: p equals n
vampirchik [111]

Answer:

Demand quantity: 6.3246

Supply quantity: 4.4721

Step-by-step explanation:

Supply equation:

p = (1/2) * q^2

Demand equation:

p = -(1/2) * q^2 + 30

(p is the price, q is the quantity)

If the price p is equal to 10, then we can calculate:

Supply quantity:

10 = 0.5 * q^2

q^2 = 20

q = 4.4721

Demand quantity:

10 = -0.5 * q^2 + 30

0.5 * q^2 = 20

q^2 = 40

q = 6.3246
