     Given the following notations, write a formula for x, the break-even sales level.  SP = Selling price per unit  FC = Total fixed cost  VC = Variable cost per unit  The demand for your hand-made skateboards, in weekly sales, is q = -2p + 700 if the selling price is $p. You are prepared to supply q = 3p - 400 per week at the price $p. What price should you sell your skateboards for so that there is neither a shortage nor a surplus?   
  
  Solution
9) for breakeven
total cost = total revenue
=>variablecost +fixed cost = total revenue
=>(VC)x +(FC)=(SP)x
=> (FC)=(SP)x-(VC)x
=>(SP)x-(VC)x =(FC)
=>x =(FC)/[(SP)-(VC)]
10)given
demand q=-2p+700
supply q=3p-400
for neither shortage nor surplus
demand =supply
-2p+700=3p-400
3p+2p=700+400
5p=1100
p=220
price at which skateboard should be sold =220$
