YOU OWN A COMPUTER STORE SELLING TWO TYPES OF LASER PRINTER. tHE FIRST TYPE A, HAS A COST OF $165 AND YOU MAKE A PROFIT OF $45 ON EACH ONR. THE SECOND TYPE B, HAS A COST OF $110 AND YOU MAKE A PROFIT OF $30 ON EACH ONE. YOU EXPECT TO SELL AT LEAST 100 LASER PRINTERS THIS MONTH AND YOU NEED TO MAKE AT LEAST $3450 PROFIT ON THEM.

A) HOW MANY OF EACH MODEL SHOULD YOU ORDER IF YOU WANT TO MINIMUM THE COST?

B) WHAT IS THE MINIMUM COST?

• A)30,70
  B)$12650
  
  Let x be the number of TYPE A laser printer bought.
  so the number of TYPE B laser printer bought = (100 -x)
  
  profit >= 3450
  x*45 + (100 - x)*30 >= 3450
  15x >= 450
  x >= 30
  
  For minimum cost, TYPE A laser printer should be bought minimum.ie x-->minimum
  so, x = 30
  
  TYPE A = 30 and TYPE B = 70
  
  minimum cost = 165*30 + 110*70
  =$12650

• A)30,70
  B)$12650
  70*30=2100
  30*45=1350 so Atype=30,B type=70
  min cost=30*165+70*110=$12650
