b) The weekly demand and supply functions for a new brand of TV are given by p = -0.2x2 + 150 and p = 0.2x2 + 0.7x + 75 respectively, where p is the unit price in dollars and x is the quantity demanded each week, in units of a hundred. a (i) Determine the unit price when there is no demand. [1 mark] (ii) Determine the quantity supplied when the unit price is set at $95. [2 marks] (iii) Determine the equilibrium price and quantity. [3 marks]

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
