33)    0.25/2ft = x/15ft    where x is the inches on the scale drawing   multiply by 15 on both sides

(15)(0.25)/ 2 = x  = 1.875 in

34)   The tiled area  = Total area - area occupied by cabinets.......

The total area is 15 x 12 =  180 sq ft

The area occupied by the cabinents is (12 x 2)  + (4 x 2 x 2)  =   24 + 16 = 40 sq ft

So  ...   180 - 40   =  140 sq ft  will be tiled (not covered by cabinets)

35) I'm taking a guess here as to what is meant......

10 cabinets will be installed.....so......the cost per cabinet is  \$(2150 - 650)/ 10   =  \$150  per cabinet

So  20 cabinets plus the fixed labor charge of \$650  =  20 x \$150 + \$650  = \$3650
